土的钻孔剪切试验及其工程应用

On drilling and shear trial for soil and the related engineering application

进行土的室内直剪试验时要取土样,对于饱和状态的粘上、粉土和砂土取样往往十分困难,且取样时扰动的影响很大。本文介绍一种对土体扰动较小的原位直接剪切试验,该方法属原位测试技术,能较好地反映出土体天然状态下的力学性能,并研究了试验注意事项和试验数据处理。

A new way is provided to be applied in the drilling and shear trial for soil, which can mostly reflect the mechanical performance under the natural condition.
