应力差值呈现以下基本规律：（1）应力差值迅速达到峰值，进而骤降并最终以

The stress difference presents the following basic rules: <br>(1) The stress difference quickly reaches the peak value, and then drops suddenly and is maintained in a smooth trend until the end of shear. This speed usually increases with the increase of the applied confining pressure, and decreases with the increase of the saturation of the test piece. The yield stress limit also maintains the same trend. <br>(2) With the increase of confining pressure, the peak value of stress difference shows an increasing trend, and the shear modulus of soil (curve slope) shows a downward trend. <br>(3) Both the peak value of the composite stress difference and the residual value after shearing have been improved, indicating that the shear resistance has been improved. <br>(4) As the water content increases, the yield stress limit of the soil increases, which is 0~2, 1~3, 5~8, 8~16, indicating that its anti-brittle strength will decrease accordingly.

应力差值呈现以下基本规律：<br>（1）应力差值迅速达到峰值，进而骤降并最终以平滑趋势保持至剪切结束。该速度通常会随施加围压增加而变快，随试件的饱和度提升而下降，屈服应力极限也保持着相同趋势。<br>（2）随着设置围压递增，应力差峰值呈递增趋势，土体切弹性模量（曲线斜率）呈现出下降趋势。<br>（3）复合体应力差峰值与剪切后残余值皆有提升，说明其抗剪能力有所提升。<br>（4）随着含水量增大，土体屈服应力极限随之增大，分别为0~2、1~3、5~8、8~16，说明其抗脆断强度会随之降低。

The stress difference shows the following basic rules:<br>(1) The stress difference reaches the peak value rapidly, then drops abruptly and finally maintains to the end of shear with a smooth trend. The velocity usually increases with the increase of confining pressure, decreases with the increase of saturation, and the yield stress limit keeps the same trend.<br>(2) With the increase of confining pressure, the peak value of stress difference increases and the shear modulus of elasticity (curve slope) decreases.<br>(3) Both the peak value of stress difference and the residual value after shearing are increased, indicating that the shear resistance of the composite is improved.<br>(4) With the increase of water content, the yield stress limit of soil increases, which are 0 ~ 2, 1 ~ 3, 5 ~ 8 and 8 ~ 16 respectively, indicating that the brittle fracture strength will decrease.
