摘　　要：本文根据山区输电线路工程实例,归纳总结了常见塔基库岸边坡变形失稳的一般形式、出现时机、主要表现特点及影响因素等;并针对库岸边坡稳定性影响较大的因素——水位下降幅度、下降速率、坡体组成物质的渗透性等,采用GEO-SLOPE及SEEP/W软件进行模拟耦合分析,在此基础上对其变形失稳机理进行了初步探讨,为输电线路工程库岸边坡塔基稳定性问题的研究及类似工程提供参考。According to engineering examples of transmission line in mountainous area,the general form、timing、main characteristics and influencing factors of deformation instability of the common reservoir bank slope of tower footing are summarized.In addition,the GEO-SLOPE and SEEP/W software were used for simulation coupling analysis on the basis of factors such as degree of water level decline、decline rate and permeability of the slope components.This paper discusses the mechanism of deformation and instability which provides a reference for the stability analysis on reservoir bank slope of tower footing in power transmission line project and similar projects.
