东昌路地铁车站降承压水引起的地面沉降研究

The research of earth subsidence induced by pumping confined water in subway station of Dongchang road

从东昌路地铁车站降承压水的实际出发,根据野外实测数据,利用降承压水理论以及降承压水的特殊工况,对水头,水头与时间的关系以及在抽水过程中水头的异常现象作出了客观的分析。并试图通过实测结果和图表的理论分析,寻找上海地区降承压水水头分布范围及其与地面沉降之间的一般规律。

The waterhead,relationship between the waterhead and time and unusual phenomena of waterhead during the phase of pumping water is objectively analysed,by using the special working condition and the theory of drawing confined water,based on the field data in sub- way station of Dongchang Road.It attempts to capture the general principle between the distribution of confined water in Shanghai region and stratum subsidence through the theoretical analysis of the testing result and the graphs.
