摘　　要：混凝土墙式防撞护栏既是保障桥梁安全运输的关键构造物,又是国内外应用最广泛的桥梁防撞护栏形式。随着我国交通运输事业的发展,车辆载重与行驶速度对桥梁安全运输功能的要求呈上升趋势。该文详述近30年来我国规范针对桥梁混凝土墙式防撞护栏设计要求的发展历程,从结构形式、防撞等级、碰撞速度及碰撞荷载等多个参数方面分析设计要求提升的具体技术体现,梳理设计理念的变化,通过对比各设计方法的主要改进与提升,总结不同时期对桥梁混凝土墙式防撞护栏性能的要求与认知,为下一阶段针对桥梁混凝土墙式防撞护栏设计技术改善提供有力的循证预判,并为有类似防撞需要的工程项目的安全实践提供借鉴。Concrete wall-type anti-collision barrier is not only a key structure to ensure the safe transportation of bridges,but also the most widely used form of bridge anti-collision barrier at home and abroad.With the development of China's transportation industry,the requirements for safe transportation functions of bridges are on the rise.This paper details the development history of China's specifications for the design requirements of bridge concrete wall-type anti-collision guardrails in the past three decades.It analyzes the specific technical manifestations of the improvement of the design requirements from multiple parameters such as structural form,anti-collision level,collision speed and collision load.This paper reviews the changes in design concepts,and summarizes the requirements and perceptions of the performance of bridge concrete wall-type anti-collision guardrails in different periods by comparing the main improvements and improvements of various design methods,so as to make a strong evidence-based prediction for the next stage of improving the design technology of bridge concrete wall-type anti-collision guardrails,and provide reference for the safety practice of engineering projects with similar anti-collision needs.
