摘要
目前遍布全国的电网工程项目大多都面临着滑坡、塌陷、泥石流等地质灾害的严重威胁。本文选取黄石冶钢变电站为研究对象,在对场地岩溶塌陷敏感性因素进行分析的基础上,对该场区各个剖面分别进行了数值模拟分析,得出了各个钻孔点岩溶顶板稳定性评价结果,从而获得了该场地岩溶地基的稳定性分布图;最后根据稳定性评价结果,并结合相关地质条件提出了相应的现场施工处理措施和防治对策,以为有效处理岩溶地基溶洞稳定性的防灾减灾工作提供参考。
Many State Grid projects of China are facing a series of natural disaster threats,such as landslide,collapse,mud-rock slide,etc.This paper takes the Huangshi Daye Steel Substation as the research object and evaluates its karst foundation stability.To obtain stability data of the karst foundation of the substation,the paper adopts the numerical simulation method to evaluate the stability of the karst foundation on the basis of sensitivity results.The paper analyses the stability evaluation results and proposes specific site operation suggestions in related geological conditions,which provides references for the disaster prevention and mitigation work for the stability of the karst foundation.
