摘要
结合某220 kV变电所真空预压工程实例,对真空预压加固软基的环境效应进行初步分析,对比分析采用水泥搅拌桩隔离、开挖应力释放沟对减小周围土体水平位移和沉降的作用,并将应力释放沟应用于防治真空预压环境影响中,供工程实践参考。
Combining with an engineering practice of 220 kV substation using vacuum preloading for soft ground treatment,through preliminary analysis of environmental effects of vacuum preloading,this paper compares the stress release trench with the cement mixing pile for reducing the horizontal displacement and settlement of surroundings,and the stress release trench shall be used for preventing environmental effects induced by vacuum preloading. Which provides a reference for project practice.
