土抗剪强度的影响因素与研究发展

Influencing Factors and Research Development of Soil Shear Strength

在生活中有许多建筑物是由于地基变形过大或不均匀发生了影响到建筑物使用或安全的事故,这种事故一方面是沉降造成的,另一方面是由土体的强度受到破坏而造成的。本研究以土体的强度为研究对象,通过土的直剪实验,分析影响土抗剪强度的因素,并提出目前土的抗剪强度研究中存在的一些问题,为进一步深入研究地基基础的设计奠定基础。

The use and safety of many buildings in our lives are affected by accidents due to excessive or uneven ground deformation.This kind of accident is caused by settlement on the one hand,and the strength of soil on the other hand.Taking the strength of soil as the research object,through the direct shear test of soil,the factors affecting the shear strength of soil are analyzed,and some problems existing in the current study of shear strength of soil are brought up in order to lay a foundation for further research on the design of building foundation.
