交通护栏是设置在路肩外侧、交通分隔带以及人行道路牙等位置的一种交通安全设施。通过自体变形或车辆爬高来吸收碰撞能量，从而改变车辆行驶方向、阻止车辆越出路外或进入对向车道、大程度地减少对乘员的伤害。Traffic guardrail is a kind of traffic safety facility which is set on the outside of shoulder, traffic partition belt and pedestrian teeth. The collision energy is absorbed by self deformation or vehicle climbing, so as to change the driving direction of the vehicle, prevent the vehicle from going out of the way or entering the opposite lane, and minimize the injury to the passengers.路旁护栏用于保护车辆及车里面的人防止受到位于道路旁边的天然或人工物件的碰撞。车辆撞击交通护栏可能既损害车辆/乘客又损害护栏本身，注意到这一点是重要的。碰撞护栏引起的损害通常不如碰撞位于护栏之后的部件严重，因此交通护栏代表了这两种考虑之间的一个折衷。除了保护车辆之外，交通护栏也用于屏蔽行人、养护/施工人员、或者来自不定交通的骑脚踏车的人。以它基本的形式，交通护栏设计用于防止离开车行道的车辆撞击固定的物体。护栏阻拦一个事故车辆，然后使其改变方向。因为车辆冲击的可变性以及高速下的破坏作用，应当引进全面的全尺寸破坏试验，以将要使用的交通护栏的安全可靠性。
可以使用的护栏有很多种尺寸和形状。护栏类型的选择取决于多种因素，包括公路所处的环境以及速度和交通量。Roadside guardrails are used to protect vehicles and people inside them from collision with natural or artificial objects located on the side of the road. It is important to note that a vehicle crashing into a traffic barrier may damage both the vehicle/passenger and the barrier itself. Traffic barriers represent a compromise between the two considerations, since the damage caused by crashing a barrier is usually less serious than that caused by crashing a component behind the barrier. In addition to protecting vehicles, traffic barriers are also used to shield pedestrians, maintenance/construction personnel, or cyclists from uncertain traffic. In its most basic form, traffic barriers are designed to prevent vehicles leaving the lane from hitting fixed objects. The guardrail first blocks an accident vehicle and then changes its direction. Because of the variability of vehicle impact and the destructive effect at high speed, comprehensive full-scale destructive test should be introduced to ensure the safety and reliability of the traffic guardrail to be used.
There are many sizes and shapes of guardrails that can be used. The choice of guardrail type depends on a variety of factors, including the environment of the highway, speed and traffic.
交通护栏的作用有：
一是防止车辆冲出路外造成翻车事故，特别是设置在山区弯道、险道处的交通护栏，对机动车驾驶员来说，在远处可引起充分的注意，使其提高警惕，在通过时还能对驾驶员进行视线诱导，帮助其进行正确操作，
二是可防止对向车发生正面冲突，同时可防止同向车发生擦、挂；
三是可防止车辆冲撞行人，并可防止行人任意横穿马路等。The functions of traffic barriers are as follows:
The first is to prevent overturning accidents caused by vehicles rushing out of the road, especially the traffic barriers located in mountain bends and dangerous roads. For motorists, they can draw sufficient attention in the distance and make them alert. They can also guide the driver's sight and help them operate correctly when passing.
Secondly, it can prevent frontal collision of the opposite car, and at the same time, it can prevent the same car from scraping and hanging.
Thirdly, it can prevent vehicles from colliding with pedestrians and pedestrians from crossing the road at will.
1．按护栏构造形式分类
(1)半刚性护栏。半刚性护栏是一种连续的梁柱结构。它是通过车辆与护栏间的摩擦、车辆与地面间的摩擦及车辆、土基和护栏本身产生一定量的弹、塑性变形(以护栏系统的变形为主)来吸收碰撞能量，延长碰撞过程的作用时间来降低车辆速度，并迫使失控车辆改变行驶方向，恢复到正常的行驶方向，从而确保乘员安全和减少车辆损坏。半刚性护栏主要设置在需要着重保护乘员安全的路段。
(2)刚性护栏。刚性护栏是一种基本不变形的护栏结构。对刚性护栏来说，是通过车轮转动角的改变，车体变位、变形和车辆与护栏、车辆与地面的摩擦来吸收碰撞能量。在碰撞过程中，车辆变形程度取决于其自身的刚度、碰撞能量和碰撞作用时间。当车辆的碰撞角度较大时，往往造成比较严重的后果。刚性护栏主要设置在需严格阻止车辆越出路外，以免引起二次事故的路段。
(3)柔性护栏。柔性护栏是一种具有较大缓冲能力的韧性护栏结构。缆索护栏是柔性护栏的主要代表形式，它是一种以数根施加初张力的缆索固定于立柱上而组成的结构，完全依靠缆索的拉应力来抵抗车辆的碰撞，吸收能量。1. Classification according to the form of guardrail construction
(1) Semi-rigid guardrail. Semi-rigid guardrail is a continuous beam-column structure. It absorbs collision energy by friction between vehicle and guardrail, friction between vehicle and ground, and elastic and plastic deformation of vehicle, soil foundation and guardrail itself (mainly deformation of guardrail system), prolongs the action time of collision process to reduce vehicle speed, and forces out-of-control vehicles to change their driving direction and return to normal driving direction, so as to ensure the safety of passengers. Reduce vehicle damage altogether. Semi-rigid guardrails are mainly located in sections where occupant safety needs to be emphatically protected.
(2) Rigid guardrail. Rigid guardrail is a basic non-deformable guardrail structure. For rigid guardrail, it absorbs collision energy by changing wheel rotation angle, body displacement, deformation and friction between vehicle and guardrail, vehicle and ground. In the process of collision, the degree of vehicle deformation depends on its stiffness, collision energy and collision action time. When the collision angle of the vehicle is large, it often causes serious consequences. Rigid guardrails are mainly set in the sections where vehicles must be strictly prevented from crossing the road to avoid secondary accidents.
(3) Flexible guardrail. Flexible fence is a kind of tough fence structure with large cushioning capacity. Cable guardrail is the main representative form of flexible guardrail. It is a structure consisting of several cables with initial tension fixed on the column. It completely relies on the tension stress of the cables to resist the collision of vehicles and absorb energy.
2．按护栏设置位置分类
(1)路侧护栏。路侧护栏是指设置在公路路肩(或边坡)上的护栏，用于防止失控车辆越出路外。碰撞路边障碍物和其他设施。
(2)中央分隔带护栏。中央分隔带护栏是指设置于道路中间在内的护栏，目的是防止失控车辆穿越中间带闯入对向车道，保护中问在内的构造物和其他设施。
(3)桥梁护栏。桥梁护栏是指设置在桥梁上的护栏，目的是防止失控车辆越出桥外，保护行人和非机动车辆。
(4)过渡段护栏。过渡段护栏是指在不同护栏断面结构形式之间平滑连接并进行刚度过渡的结构段。
(5)端部护栏。端部护栏是指在护栏开始端或结束端所设置的结构。
(6)防撞垫。防撞垫是通过吸能系统使正面、侧面碰撞的车辆平稳地停住或改变行驶方向，一般设置在互通立交出口三角区、未保护的桥墩、结构支撑柱和护栏端头。2. Classification by location of guardrail
(1) roadside guardrails. Roadside guardrail refers to the guardrail set on the road shoulder (or slope), which is used to prevent out of control vehicles from crossing the road. Collision with roadside obstacles and other facilities.
(2) Central partition with guardrail. The central partition barrier is a barrier set in the middle of the road to prevent out-of-control vehicles from entering the opposite lane through the middle zone and to protect the structures and other facilities.
(3) Bridge guardrail. Bridge guardrail refers to the guardrail installed on the bridge to prevent out-of-control vehicles from crossing the bridge and protect pedestrians and non-motor vehicles.
(4) transitional barrier. Transition section guardrail refers to the structural section which smoothly connects and carries out rigidity transition between different sections of guardrail.
(5) End guardrail. End guardrail is a special structure set at the beginning or end of guardrail.
(6) Anti-collision cushion. Anti-collision cushion is used to stop or change the driving direction of vehicles with frontal and side collisions through energy absorption system. It is usually set at the exit triangle of interchange, unprotected piers, structural support pillars and guardrail ends.1．交通护栏的检查
交通护栏检查包括日常检查和每季度定期检查，检查内容如下：
(1)各类护栏结构部分有无损坏或变形，立柱与水平构件的紧固状况。
(2)污秽程度及油漆状况。
(3)拉索的松弛程度。
(4)护栏及反光膜的缺损情况。
2．养护与维修
(1)经常清除护栏周围的杂草及其他堆积杂物。
(2)护栏表面油漆脱落应及时涂刷。
(3)由于交通事故或自然灾害造成护栏缺损或变形要及时补充或更换。
(4)由于路面补强或调整路基纵断面，使护栏标高发生显著变化的，应对护栏的高度予以相应的调整。
(5)锈蚀严重的护栏应予以更换。1. Inspection of traffic barriers
Traffic barrier inspection includes routine inspection and quarterly periodic inspection. The inspection contents are as follows:
(1) There are no damage or deformation in all kinds of guardrail structures, and the fastening condition of columns and horizontal members.
(2) Degree of contamination and paint condition.
(3) The degree of relaxation of cables.
(4) The defect of guardrail and reflective film.
2. Maintenance and maintenance
(1) Frequently remove weeds and other accumulated debris around the guardrail.
(2) The paint on the guardrail surface should be painted in time when it falls off.
(3) The barrier defect or deformation caused by traffic accidents or natural disasters should be replaced or replaced in time.
(4) The height of the guardrail should be adjusted accordingly because the pavement is reinforced or the roadbed profile is adjusted, which makes the elevation of the guardrail change significantly.
(5) The badly corroded guardrail should be replaced.
今天，33岁的魏晨发微博晒出一段水下视频。视频中，魏晨在水下拿着一枚戒指游向女友，而同样在水下的女友看到戒指，相当感动，还用手捂住了潜水罩！而魏晨也配文表示：“Yes，I DO ”宣告向女友求婚成功！这是一场非常突如的求婚，连网友都：“魏晨居然有女友了！”可是魏晨的粉丝还是比较淡定，因为他们一直都知道偶像早已有女友，并且都十分支持他！还向路人解释：魏晨和女友已经十几年了，只是女友是圈外人，所以他们粉丝也会一直好好保护她，还大赞魏晨真的很专一！魏晨的女友名叫于玮，两人是四川音乐学院的同学。大学期间两人就在一起了，于玮毕业后曾经也出道过，曾是国内首支少女偶像组合Idol girls中的一员，以前她还参加过《闯关上梁山》。2015年两人被拍到在爱巢甜蜜相拥，还一起做饭，随后魏晨发微博默认恋情，2016年6月，二人一起现身机场，合体公开亮相，低调相恋十多年终于修成正果。我们都知道，魏晨是2007年快男季军出道。出道后，就出演了大爆偶像剧《一起看流星雨》，事业红火。但之后魏晨的事业却有所沉寂，不管是音乐还是影视这块，都没有大亮成绩。2015年，魏晨成立了个人工作室，除开音乐，他也开始尝试更多的影视剧集！
