in plane shear test 面内剪切试验
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。
As to the shear strength mobilized in drained test, both of these two components are related with the effective normal stress on the failure plane.
而在排水试验中，则这两部分强度均对应于破坏时的有效应力。
