安徽某变电站膨胀土地基处理方案研究

安徽省是我国膨胀土的主要分布地区之一,全省膨胀土分布总面积约41742.41 km2。变电站工程安全等级高,数量多,在该省内分布广泛,因此,膨胀土对变电站建设影响较大。该文具体以变电站工程为例,分析变电站内典型建(构)筑物特点,并提出具体的处理措施,以消除膨胀性的不利影响,同时也对施工、运维阶段提出合理建议。

Anhui Province is one of the main areas with the distributionof expansive soil in China,and the total area of expansive soil in Anhui Province is about 41742.41 km2.The safety level of the substation project is high,the quantity is large,and it is widely distributed in the province,so the expansive soil has a great influence on the substation construction.Taking the substation project as an example,this paper analyzes the characteristics of the typical structures in the substation,and puts forward specific treatment measures to eliminate the adverse effects of expansibility,and also puts forward reasonable suggestions for the construction,operation and maintenance stages.
