摘　　要：上海地区与工程建设密切相关的承压水主要赋存于微承压、第一、第二承压含水层中。本文在上海市区关键土层地质编图的基础上,针对与工程建设密切相关的承压含水层的分布特征,进行承压含水层的结构类型分区,为工程降水设计提供参考。The confined water in Shanghai which is tightly related to the engineering mainly include less confined water, No. 1 confined water and No. 2 confined water. According to the distribution characteristics, this paper zoned for structural type of confined water bearing layer, which provided a reference for engineering dewatering.
