set of shears meaning in English

切变组

The pore pressure , relationship of stress and strain , and the shear strength parameters obtained by unloading tests are different from those obtained by loading tri - axial tests . later the difference is analyzed in the respect of stress path and microstructure . at last , by use of a practical project the author compared and analyzed the two sets of shear strength parameters obtained by two different stress paths
模拟基坑开挖的三轴试验得出了与常规三轴试验不同的孔隙水压力和应力-应变关系，这样得到的抗剪强度指标也低于常规三轴固结不排水加荷试验所得抗剪强度指标，继而本论文对抗剪强度指标的差异从应力路径的角度和微观结构的角度进行了分析。
