巴基斯坦某电站近坝冲沟泥石流地质调查及其对坝影响评价
|
摘要
泥石流是工程地质基础中常见的物理地质现象之一,作为水电站建设工程中的重大危险源,也是电站库区勘察中必须说明和解决的主要的工程地质问题之一,尤其是近坝泥石流直接决定了项目工程的选址或坝址枢纽布置。依据相关规程规范对巴基斯坦某水电站近坝冲沟(KAS沟)开展泥石流地质调查,在野外地质工程勘察的基础上,结合一些简单的坑探勘察手法,对其易发程度进行评分、判别和类型划分,并就其对坝址的影响作出工程地质评价。
Debris flow is one of the common physical and geological phenomena in engineering geology foundation.As a major hazard source in hydropower project construction,it is also one of the main engineering geological problems that must be explained and solved in the investigation of reservoir area of hydropower station,especially the site selection of project projects or the layout of dam sites directly determined by Near-dam debris flow.Debris flow geology survey is carried out in a KAS ditch near a dam of a hydropower station in Pakistan according to relevant rules and regulations.On the basis of field geological engineering survey and combined with some simple pit exploration techniques,the susceptibility degree is scored,distinguished and classified,and its influence on dam site is evaluated in engineering geology.
