浙江省山区输电线路塔位边坡变形破坏主要类型与防治建议

Main types of deformation and failure of transmission line tower slope in mountainous areas of Zhejiang Province and prevention suggestions

山区输电线路铁塔基础施工改变了塔位附近原始微地形、覆盖植被等环境地质条件,岩土体内部原有应力状态发生了变化,在各种自然营力作用下,每年在浙江省山区会发生一定数量塔位边坡的变形与破坏。根据影响因素、变形破坏机理分析,结合现场勘查及实际情况,划分为坍塌、滑坡、流坍等边坡变形破坏类型,经研究总结得出其主要发育特征,并提出了防治建议。

The construction of transmission line tower foundation in mountainous area has changed the original micro terrain near the tower site,covered vegetation and other environmental geological conditions.The original stress state inside the rock and soil has changed.Under the action of various natural forces,a certain number of tower slope deformation and failure will occur in mountain area of Zhejiang Province every year.According to the analysis of influencing factors,deformation and failure mechanism,combined with field investigation and actual situation,it is divided into collapse,landslides,flow collapse;The main developmental characteristics were summarized;The prevention and control suggestions of slope deformation and failure are put forward.
