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。
Based on the experiment of indoor precipitation of Yishan Road Station on line 9 of Shanghai Metro and on the basis of sorting out and analyzing various monitoring data such as water level and flow in the well, pore water pressure, stratified settlement and surface subsidence, The relationship between the various influencing factors during precipitation was analyzed, which provided better design experience and improvement plan for the subsequent project precipitation and ensured the safety of the foundation pit construction and the overall stability of the envelope structure.
