超高压输电线路塔基滑坡灾害特征分析与治理
|
摘要
为研究超高压输电线路塔基滑坡特征与治理措施,以黄(岩)达(州)线157号塔滑坡灾害为例,结合滑坡区域内主要地质环境与水文气象条件,分析了滑坡的发育特征、灾害特点、成因机理及发展趋势。并针对区域构造与地表水等影响滑坡的主要因素,提出了以截排水、填埋裂缝、增设抗滑桩等工程措施为主,塔基变形和位移监测相结合的综合减灾防灾措施,为今后治理输电线路塔基滑坡地质灾害提供了经验借鉴。
To research the characteristics and treatment measures of landslide disaster along the tower foundation in EHV transmission lines,taking the 157 tower landslide disaster in Huangyan-Daxian EHV transmission line as an example,the development characteristics,disaster characteristics,formation mechanism and development trend of the landslide were analyzed,combined with the geological environment and hydro-meteorological conditions in the landslide area. According to the main influence factors of landslide,such as regional structure,surface water and so on,comprehensive disaster mitigation measures were suggested,which mainly adopted drainages system,cracks filling and anti-slide pile,and was in combination with the deformation and displacement monitoring of tower foundation. All of these measures can provide references for the treatment measures of landslide geological disasters in transmission lines in the future.
