天水屈坪村滑坡稳定性分析及整治措施研究
摘要:天水南北两山地区滑坡灾害极其发育，在此区域修建公路极具挑战。以天水屈坪村大型牵引式堆积层滑坡分析与整治为例，采取工程地质调绘、钻探、深部位移监测及室内力学试验方法，分析该滑坡的形态、变形及发育特征，研究滑坡成灾机理并评价其稳定性，并提出整治措施。结果表明，屈坪村滑坡在平面形态上分前后两级，滑动方向为折线型，滑体主要由粉质黏土组成，滑床为新近系泥岩，为一典型堆积层滑坡。滑面埋深6.0～13.0 m，变形方式为牵引式，诱发原因为坡体地质环境加地震、强降雨等自然因素。针对该滑坡，提出截排水、支挡、监测的一套整治方案，为其它沿线类似滑坡灾害治理提供参考。
Abstract:The landslide disasters in the north and south mountain areas of Tianshui are extremely developed, and it is extremely challenging to build roads in this area. Taking the analysis and remediation of a large tractive deposit landslide in Quping village, Tianshui as an example, engineering geological mapping, drilling, deep displacement monitoring, and indoor mechanical tests were conducted to analyze the form, deformation, and development characteristics of the landslide. The disaster mechanism of the landslide was studied and its stability was evaluated, and remediation measures were provided. The results show that the Quping landslide could be divided into two stages in plane morphology, the sliding direction is broken line, the sliding body is mainly composed of silty clay, and the sliding bed is Neogene mudstone, which is a typical accumulation landslide. The buried depth of the sliding surface is 6.0~13.0 m, and the deformation mode is traction type, which is induced by the geological environment of the slope, earthquake, heavy rainfall, and other natural factors. In view of the landslide, a set of treatment plans such as drainage interception, retaining, and monitoring was put forward, which can provide a reference for the control of similar landslide disasters.
