聚苯乙烯泡沫(EPS)在道路工程中的应用

The Applications of Expanded Polystyrene(EPS) Foam in Road Engineering

在研究分析EPS物理力学特性的基础上，对EPS在道路工程中的应用进行了归纳分类。并结合沪宁高速公路拓宽工程EPS路堤填筑试验，研究了拼接路堤结构形式、防撞护栏的设计方法，介绍了EPS纵横向连接及铺设、路堤排水处理等施工方法。

Based on the analysis of physical and mechanical characteristics of EPS, the applications of EPS in road engineering are summed up and classified in this paper. Combining with the EPS embankment study in the widening project of Shanghai-Nanjing expressway, the structural style of splicing embankment and the design of the anticollision guardrail are studied. The paper also introduces the job practice of EPS to be vertical-horizontal to connect and lay, draining water processing about embankment, which has consultative function of utilizing EPS in similar project.
