摘 要：传统波形梁钢护栏施工技术合格率较低，因此有必要研究公路波形梁钢护栏工程安全施工技术。一是检验施工材料是否满足公路波形梁钢护栏工程安全施工要求;二是根据不同施工路段性质，选择合理方法对立柱进行安装;三是车辆碰撞耦合非线性方程，计算公路波形梁钢护栏碰撞力;四是运用螺栓和锚固件将波形梁钢护板与立柱进行拼接，一次完成公路波形梁钢护栏工程安全施工。试验证明，采用设计方法施工的波形梁钢护栏合格率平均值超过94%，远远高于传统技术。

Abstract： The qualification rate of traditional corrugated beam steel guardrail construction technology is low， so it is necessary to study the safe construction technology of highway corrugated beam steel guardrail project. The first is to check whether the construction materials meet the safety construction requirements of the highway wave beam steel guardrail project; the second is to choose a reasonable method to install the columns according to the nature of different construction sections; the third is the vehicle-coupling nonlinear equation to calculate the collision force of the corrugated beam steel guardrail of the highway; the fourth is to use the bolts and anchors to splice the corrugated beam steel guard plate and the column， and complete the safety construction of the highway corrugated beam steel guardrail project at one time. The test proves that the average passing rate of the corrugated beam steel guardrail constructed by the design method exceeds 94%， which is much higher than the traditional technology.

1.1 检验公路波形梁钢护栏工程施工材料

公路波形梁钢护栏工程施工过程中，最主要的施工材料为波形梁钢护栏，波形梁钢护栏质量的好坏将直接关系到整个工程的施工质量，但是不同公路路段在项目施工中所使用的波形梁钢护栏种类是不同的。在公路波形梁钢护栏工程施工前，为了保障工程施工安全与施工质量，人们需要对公路波形梁钢护栏施工材料进行检验。……
