川藏输电线西藏段杆塔地质灾害分析

Geological Hazard Analysis of Poles and Towers in Tibet Section of Sichuan-Tibet Transmission Line

以川藏联网输电线路工程西藏段为例,通过对沿线影响杆塔安全的地质灾害问题进行调查分析,总结地质灾害发育特征,得出藏东高寒山区影响杆塔安全的地质灾害类型主要包括:滑坡、崩塌(滚石)、不稳定斜坡、泥石流等。通过分析这几种地质灾害类型对杆塔稳定性影响的机理,为提出合理可靠的处置措施提供理论依据,对类似工程具有一定的参考作用。

Taking the Tibet section of Sichuan-Tibet interconnected electric transmission line project as an example, by investigating and analyzing the geological hazards affecting the safety of poles and towers along the line, the development characteristics of geological hazards are summarized. It is concluded that the main types of geological hazards affecting the safety of poles and towers in the alpine mountainous areas of Eastern Tibet include landslide, collapse (rolling stone), unstable slope and debris flow.summarized the development of features of geological disasters, eastern Tibet alpine mountains affect drawn tower safe geological hazard types include: landslide, collapse (Rolling Stones), unstable slopes, landslides and so on. By analyzing the influence mechanism of these types of geological hazards on the stability of the tower, this paper provides a theoretical basis for putting forward reasonable and reliable disposal measures, and has a certain reference role for similar projects.
