摘要
应用突变理论对某层状岩体滑坡进行了研究 ,用弹性力学理论综合考虑地下水因素建立了尖点突变模型 ,分析了滑坡的形成机制 ,认为地下水主要是通过物理化学作用软化了滑面带岩体 ,使滑面带岩体刚度比降低 ,从而使岩体突发失稳 ,地下水的力学作用表现为一种触发因素。并进一步根据突变理论提出了防治建议。
On the basis of catastrophic theory ,a catastrophic model with cusp point for stratified rock mass with a gentle inclination is developed by using elastic mechanics theory .This model studies groundwater effect in a comprehensive way for the first time. Also, this model indicates that groundwater softens the rock mass of slide surface by the physicochemical effect and reduces rigidity ratio of the rock mass, and leads to sudden instability. Furthermore, the origin of landslide is discussed and some suggestions of harnessing the landslide are presented.
