宝鸡市狄家坡斜坡是一个古滑坡。在调查滑坡区水文地质和工程地质条件的前提下,本文描述了滑坡的形态与物质结构、滑坡表层的变形破坏特征及其影响因素,探讨了古滑坡的发生机制。引用可以任意条分块体的Sarma方法,研究了该滑坡在自然、地震、饱水和三者同时存在共四种状态下的稳定性,并进行了斜坡表层黄土坡体的稳定性对于地下水位上升的敏感性分析。基本结论是,狄家坡滑坡在整体上是稳定的,其表层的黄土坡体在地下水位上升时会发生失稳破坏。最后,提出了进行滑坡防治的工程对策。
Baoji Di Jiapo slope is an ancient landslide. Under the premise of investigating hydrogeology and engineering geological conditions in landslide area, this paper describes the shape and material structure of landslide, the deformation and damage characteristics of landslide surface and its influencing factors, and discusses the mechanism of the ancient landslide. The Sarma method, which can be divided into arbitrary blocks, is used to study the stability of the landslide under four conditions of natural, seismic, saturated water and coexistence of the three, and the stability of loess slope on the slope surface is studied. Rising sensitivity analysis. The basic conclusion is that the Dijiapo landslide is stable as a whole, and the loess slopes on the surface of the landslide will be instably damaged when the water table rises. Finally, the engineering measures for landslide prevention and control are put forward.
