摘要
基坑开挖若采取慢速施工或者人工开挖的方法,由于土层透水性能好,基坑中水比较容易排出,通常近似认为固结排水过程。文章介绍的是在真三轴上模拟基坑开挖周边土体的应力路径,进行了排水卸荷试验,通过对试验成果的研究,分析了卸荷排水状态下土体的变形性质。
If foundation pit excavation adopts the method of slow construction or artificially excavation,because the soil layer water percolation performance is good,the water in the excavated hole is easy to discharge,usual approximately thought solid draining process.This article simulates stress path of the foundation pit excavation peripheral soil body on the triaxial drained test,makes unloading draining water test.Through experiments achievement research,analyzes soil body distortion nature under the conditons of unloading water process.
