摘要
通过预先埋设的设备,对泡沫轻质土加宽高速公路路基的受力特性进行了实际观测与分析,得出了泡沫轻质土填筑高速公路加宽路基时的受力规律,为高速公路扩建工程的断面优化打下了基础。
Through the embedded devices in advance, the stress characteristics of foamed light -weight soil widening expre- ssway subgrade were observed actually and analyzed in this paper. The mechanical rules of foamed light -weight soil wide- ning expressway subgrade were concluded. It can be used to optimize the section pattern of expressway widening project.
