Taking the expensive soil in Nanyang Area, Henan Province, as study case, the in-situ shear test method, including preparing samples and test method, is proposed in the paper.

结合南阳地区膨胀土的抗剪强度研究，对其现场剪切试验的试样制备及试验方法进行探讨，提出了膨胀土抗剪强度的修改计算公式。

So a split-type shear box is adopted to conduct the in-situ shear test in order to make the stress on the shear plane uniform and ensure the shear stress to running through the center o.

我们改进后采用分体式剪切盒进行原位土体试验，使剪切面上的应力分布均匀，保证剪力通过剪切缝中心，同时在试验过程中法向及剪向加载时试体稳定性得到了很好的改善。
