摘要
基于滑坡体结构发展趋势的链式原理,建立起滑坡为结构体的模型并进行理论分析。滑坡属于地质力学的范畴,建立适当的力学结构模型,进行理论上的应力应变分析。通过灾害链式理论的指导,具体分析降雨对滑坡体发育的链式过程,发现滑坡体发展趋势,并通过有限元进行模拟,推测滑坡体稳定的极限状态,在降雨发生情况下,判断滑坡体是否处于稳定或即将出现滑坡提供理论参考。
Landslide in the Development based on the chain principle,to establish landslide for the structure of the model theory.Landslide is the scope of geomechanics,the establishment of an appropriate model of the mechanical structure,the theoretical stress and strain analysis.Disaster chain through the guidance of theory,detailed analysis of rainfall on landslide development of chain processes,development trends that landslide,and the finite element simulation,suggesting stabilization of the limit state landslide for us in the case of rainfall occurred,to determine landslide is in a stable or imminent landslide,to provide a theoretical frame of reference.
