考虑到天然黏土不等向固结历史的影响,试验土样在循环剪切前均先K0固结至原位应力状态。
Taking the stress-induced anisotropy into account, all the specimens are initially restored to the in-situ stress state under K0 consolidation.
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。
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.
而原位松质骨块植入后的应力曲线几乎与正常应力曲线重合。
After the bone graft in situ, the stress curve was almost coincided with that of the intact femur.
