摘要 以徐州沙虎山滑坡为例,在野外工程地质测绘、钻探、室内试验基础上,论文运用三维有限差分软件FLAC3D结合极限平衡理论,分析了不同工况下该滑坡的稳定性,对滑坡的发展趋势进行了预测。结果显示:该滑坡在天然状态下处于稳定状态;暴雨状态下处于不稳定状态。该研究成果,对滑坡在不确定因素下发生的状况进行了预测,对一般边坡的稳定性预防和治理提供了一定的借鉴意义,滑坡在治理过程中对其变形部位应重点控制,采取截排水措施,在雨季重点做好对滑坡的变形监测。 The purpose of this paper is to understand the formation mechanism of the stability of the Shahushan slope. Taking the Shahushan landslide in Xuzhou as an example, based on the field engineering geological mapping, drilling and laboratory tests, this paper uses the three-dimensional finite difference software FLAC3D combined with the limit equilibrium theory to analyze the stability of the landslide under different working conditions and the development of the landslide. The results show that the landslide is in a stable state in the natural state;it is in an unstable state in the rainstorm state. The research results predict the occurrence of landslide under uncertain factors, and provide some reference for the stability prevention and treatment of general slopes. The landslide should be controlled by its deformation part during the treatment process. Drainage measures should be taken and focus on the deformation monitoring of landslides during the rainy season.
