内陆盐湖环境输电线路沿线软弱盐渍土工程特性及工程对策探讨

Discussion on Engineering Characteristics and Countermeasures of Weak Saline Soil along Qarhan Salt Lake Area Power Transmission Line

察尔汗地区有多条输电线路穿越盐湖工业采矿区,而输电线路沿线软弱盐渍土特有的工程特性和塔基附近复杂的影响因素对输电线路勘察、设计、施工及后期安全运维有重大影响。本文以察尔汗盐湖软弱盐渍土区输电线路工程建设为研究重点,在已有研究资料和现场岩土勘察成果基础上,总结软弱盐渍土的工程特性,分析盐湖软弱盐渍土区铁塔基础稳定影响因素,最后对输电线路建设的工程对策给出建议,以期为内陆盐湖软弱盐渍土地区输电线路工程建设提供参考。

There are many power transmission lines passing through the industrial mining area of Qarhan Salt Lake,and the special engineering characteristics of weak saline soil along the power transmission line and the complex influencing factors near the tower foundation have a great impact on the survey,design,construction and later safety operation and maintenance of the transmission line.This paper focuses on the construction of transmission lines in the weak saline soil area of the Qarhan Salt Lake,summarizes the engineering characteristics of the weak saline soil along the transmission line in Qarhan Salt Lake area,analyzes the factors affecting the stability of the tower foundation in the weak saline soil area,and finally gives some suggestions in order to provide reference for the construction of the transmission line in the weak saline soil area of the inland salt lake.
