上海地铁宜山路站室内降水大型模型试验分析

Analysis of the Large Indoor Model Test on Water Drainage for Yishanlu Metro Station in Shanghai

通过对上海地铁九号线宜山路站的室内降水实验,并在整理和分析了降水井水位和流量、孔隙水压力、分层沉降量、地表沉降量等各种监测数据的基础上,总结出了降水时各影响因素之间的关系,为之后的工程降水提供较好的设计经验和改善方案,确保了该地铁基坑工程施工的安全性和围护结构的整体稳定性。

After the indoor testing of water drainage for Yishanlu station in Shanghai metro line 9, and based on the processing and analysis of monitoring data about the water level and flux of the drain hole, pore water pressure, layered settlement and surface soil settlement, in this paper the relations between different factors during water drainage have been put forward and better design experiences and blue prints for water drainage are offered to ensure safety of metro pit construction and the stability of the enclosure structure.
