基于欧洲标准的圆管涵包封设计及应用

Based on european standards encapsulation pipe culvert design and application

以阿尔及利亚项目为工程背景,以圆管涵作为研究对象,采用外包混凝土的措施对圆管涵进行优化,提出了两种包封方案,分别计算和分析了使用阶段应力情况,通过计算结果可知圆管涵包封混凝土后承载力显著提高,可应用于高填土路段。

Based on the engineering background of Algeria project,used pipe culvert as the research object,the paper adopt the measure of encapsulating concrete to optimize the pipe culvert,put forward two encapsulation scheme,and separately analyzed the stress situation of ELS phase. Through calculating result we know the bearing capacity of encapsulating concrete pipe culvert was significantly increased. And the encapsulating concrete pipe culvert can be applied to highly-filled soil road.
