摘要
结合软土地区深基坑工程地下水回灌案例,发现回灌期间坑外被保护建筑持续沉降,为控制这部分沉降,对提出的双回灌井回灌策略进行了数值分析,研究了副回灌井的回灌量对双井回灌控沉效果的影响,并得到不同条件下使得受保护建筑不发生沉降时的副回灌井回灌量的取值规律。
In this study,a case study of artificial recharge for settlement control in deep excavation is reported.The surrounding protected building settles continuously during artificial recharge.In order to control the building settlement,numerical simulation is conducted to investigate the effect of coupled recharge proposed.The influence of recharge rate of auxiliary recharge well on the control effect of coupled recharge is studied by a series of numerical analyses.The critical recharge rates of auxiliary recharge well under which the surrounding protected building will not settle during the artificial recharge are obtained.
