摘要: 结合上海自来水市南有限公司广元路泵站迁建工程基坑围护工程的实践，在基坑开挖过程中，对基坑变形的发展及对周围环境进行监测和控制，由于施工方案根据时空效应理论采用了分层分区的开挖方式，减少了无支撑的暴露时间，监测结果论证了在基坑开挖的过程中时空效应理论的可靠性和有效性。

Abstract: Combining with the practice of deep excavation support project of the pump station of Guangyuan Road in Shanghai, it was carried out the monitorings and controls of the excavation deformation and surrounding environment during the deep excavation.According to the theory of time-space dependent effect the construction was done by layers and zonation, which shortened the interval without support.The reliability and effectiveness of the theory of time-space dependent effect during the deep excavation are verified by the monitoring results.
