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异常现象作了分析。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层沉降之间的一般规律 Based on the field actual data and using the theory of lowering pressure and water pressure and the special conditions of lowering pressure water, the relationship between water head, water head and time and the abnormality of water head in pumping process Phenomenon was analyzed. And tries to find out the general rules of pressure drop, head distribution and its relation with strata settlement in Shanghai through the measured results and the theoretical analysis of the chart
