将近水平地层滑坡视为一个系统,针对其平面失稳问题,在建立力学模型的基础上,运用势函数突变模型,从理论上推导了滑坡系统失稳的力学破坏判据和滑带土的临界变形位移。根据近水平地层滑坡演化系统,结合万州区安乐寺滑坡实例,运用所推导出的滑带土临界变形位移公式,得出临界位移约为34mm,并同时提出系统和临界突变状态的差距与外界环境因素——滑坡后缘裂隙积水深度、滑带土含水量的关系,即当滑坡后缘裂隙积水深度和滑带土含水量越大时,系统与临界突变状态的差距越小,滑坡越容易滑动。
The near-horizontal formation landslide is regarded as a system. Based on the establishment of the mechanical model and the abrupt change of potential function, aiming at the problem of plane instability, the mechanical failure criterion of landslide system instability and the critical of slip-soil are derived theoretically Deformation displacement. Based on the near-horizontal landslide evolution system and the example of Anle Temple landslide in Wanzhou District, the critical displacement of the landslide soil is deduced. The critical displacement is about 34mm. At the same time, the gap between the system and the critical sudden state and the external environment Factors - the relationship between the water depth of the landslide fissure and the soil water content of the landslide, that is, when the water depth of the landslide fissure and the water content of the landslide soil are larger, the difference between the system and the critical sudden change state is smaller. Easy to slide.
