The characteristics of the rock strength and failure under triaxial compressions are theoretically analyzed in detail with the twinsheartheory and the results are compared with experimental data.
应用双剪理论对岩石在三轴压缩载荷下的强度和破坏特性进行了理论分析，并将分析结果与已有实验作了对比。

The twinshear strength theory to compute the strength of gun barrels is used. The effect of strength-difference and axial stress are considered. The calculating result is more convinced.
现利用双剪强度理论计算火炮身管的强度，考虑了材料的拉压异性影响和轴向应力的作用，计算结果更为可信。
