摘要
基坑开挖会造成周边沉降变形,为减少沉降对周边环境的损害,须采取相应措施控制围护结构的变形。某地铁车站深基坑工程,通过模拟计算调整支撑刚度、围护墙体刚度和坑周土体强度等3种不同加固措施条件下基坑开挖引起的土体损失变化,并对不同加固措施进行施工成本分析,选择最经济合理的基坑加固方案。
Surrounding settlement will be induced by the foundation exaction, in order to reduce the damage to the surrounding environment for the settlement, multifarious methods to control the deformation of the retaining structure will be applied. This paper takes one deep foundation pit of a subway station as a example to compare the ground loss for different retaining methods, such as adjusting the stiffness of inner support and wall, or adjusting the strength of soil. Through the comparative analysis, the most economically retaining methods and be found.
