对岩石边坡的卸荷和流变作了非连续变形分析。指出边坡在卸荷情况下，岩体的变形分析应考虑开裂等非连续变形。对其流变变形也应考虑开裂和裂隙扩展机制进行计算才能得到岩坡的大变形与真实变形。常规弹塑性分析一般只能得到小变形，与实测值往往对应不起来。本文提出了开裂卸荷条件下岩石的本构关系和计算方法，并运用于工程。将实测结果和计算做了对比，两者甚为吻合。
Non-continuous deformation analysis of rock slope unloading and rheology was made. It is pointed out that under the condition of unloading, the deformation analysis of rock mass should consider the discontinuous deformation such as cracking. The rheological deformation of the rock slope should also consider the crack and crack expansion mechanism to calculate the rock slope can be large deformation and real deformation. Conventional elasto-plastic analysis generally only get small deformation, and the measured value often does not correspond. In this paper, the constitutive relationship and calculation method of rock under the condition of cracking and unloading are put forward and applied to engineering. The measured results and calculations made a comparison, the two are very consistent.
