对影响逆倾层状边坡稳定性因素的模型试验研究

在工程地质分析的基础上，根据相似理论建立了地质力学模型，研究了逆倾层状边坡岩体的变形破坏机制。介绍了模型试验的设计，并研究了逆倾边坡的稳定性以及岩层的倾角、厚度、结构面的强度对边坡稳定性的影响。结果表明，逆倾层状岩体的变形机制为倾倒变形，破坏模式为弯折破坏；破坏首先在坡顶产生，边坡变形加速的过程是在开挖结束一段时间后才出现；岩层倾角越小，变形加速所持续的时间越长；岩层的厚度和结构面的强度越大变形越小。

Experimentation research on factors influencing stability of anti-dip layered slope

Contraposing the concrete project, a geomechanical model is established based on the analysis of engineering geology and theory of similarity; and it is used for research on distortion and breakage mechanism of inverve-dip layered slops rock mass. The design of experimentation is described; and the stability of inverse-dip layered slope is analyzed. At the same time, it is researched that the stability of inverse-dip layered slope when terrane obliquity, terrane thickness and intensity of terrane interface are transformed. The results show that the distortion is collapse; and the brakage is disjunction; the breakage firstly come into being at the tip of slope; the accelerated distortion is late forexcavation, the terrane obliquity is bigger and the duration is longer; the terrane thickness and intensity of terrane interface are bigger and the size of the rock mass distortion is smaller.
