护栏板是一种吸能结构, 在阻止车辆越出公 路的同时, 还通过变形来吸收碰撞能量, 改变车辆方 向, 较大限度地减少事故损失。 全护栏板是减少交通事故和降低事故恶性程度的有效 措施, 但在不该设置护栏板的地方设置护栏板, 反而成为 新的障碍物, 增加了事故危险。因此, 对护栏板的设计要掌握护栏板的特点, 结合高速公路的交通 条件, 在满足护栏板基本功能的前提下, 选用合适的护 栏形式, 并采取合理的设置原则。
Guardrail is an energy absorbing structure and to stop vehicles exceed the public road at the same time, but also through the deformation to absorb the collision energy, change the vehicle to maximize reduce accident losses. Full protecting balustrade is reducing traffic accidents and reduce accident malignant degree of effective measures, but in the setting of rail fence plate is arranged. On the contrary, they become new obstacle, increases the risk of accide波形护栏标准nts. Therefore, the guardrail plate design must first grasp the characteristics of rail, combined with highway traffic conditions, under the premise of satisfying the basic functions of the guardrail plate, selection of suitable protection bar form, and take a rational set of principles.
护栏板分类与设计条件 护栏板分类 护栏板的形式按刚度的不同可分为 柔性护 由于受到地形条件、 投资和技术条件等多种因 素的制约, 路侧难免存在障碍物, 对越出路外的车辆 构成潜在的危险。路侧护栏板仅设置在能降低事故严 重度的地方, 其设计原则根据人们对公路等级、 交通 量、 车辆组成和路侧特征等因素的主观判断而确定。
Guardrail plate classification and design conditions guardrail plate classificatio公路波形梁钢护栏标准n guardrail plate in the form of the stiffness can be divided into flexible support due to a variety of terrain conditions, investment and technical conditions, because of the restriction of, roadside inevitably there are obstacles, vehicles on the way constitute a potential danger. Roadside guardrail plate disposed on only can reduce the accident severity, and its design principle based on people's subjective judgment on the highway, traffic volume, vehicle composition and roadside features such as factors to determine.
护栏板形式选择 较理想的护栏板形式是既满足功能需要又成本较 低, 而且美观大方, 并能诱导行车视线。缆索护栏板适 合有不均匀下沉、 积雪、 长直线、 有特殊美观要求的 路段; 砼护 栏适合特别危险的 跨河大桥、 悬崖等路 段; 波形护栏有更大的适用性, 基本适合所有路段, 特别是小半径弯道和需要诱导视线的路段。 根据规范要求和湖南省多条高速公路护栏板 设计经验, 一般路段路侧采用波形梁护栏板, 个别特别 困难危险路段采用砼护栏板xf1116663
The form selection of the fence board is the most ideal form of the fence board, which can meet the needs of the function, the lowest cost, and the beautiful appearance, and can induce the driving line of sight. Cable guardrail board suitable for uneven sinking, the snow, the length of a straight line, special aesthetic requirements of road; concrete guardrail for particularly dangerous cross river bridge and Cliff Road; waveform guardrail have greater applicability, is basically suitable for all road segments, especially small radius curve and needed to induce eye sections. According to the specification requirements and Hunan Province a plurality of freeway guardrail board design experience and general sections of roadside the W-beam guardrail plate, the dangerous sections of particular difficulties with concrete guardrail plate
