基坑失稳时土的各向异性对管线的位移影响

Analysis of the effect on buried pipelines' displacement causedby the anisotropies of the soil while the foundation pit being unstable

在考虑粘土的各向异性时,对由外因引起的基坑失稳而导致的位于基坑附近,且与基坑方向成一角度的管道的变形进行了分析,得到了在考虑粘土的各向异性时,计算弯曲变形和拉伸变形的公式,并对计算结果进行了分析,得到了一些有益的结果。

Considering the anisotropies of the soil, this paper analyzes the bended deformation and tensile deformation of the pipeline, which is near foundation pit and angles with the unstable foundation pit caused by the outer factors, and concludes the bended deformation＇ and tensile deformation＇ expressions of the pipeline. This paper finally analyzes the calculated result and gains some beneficial outcomes.
