基于邻近黄浦江地区承压含水层埋藏深度和厚度的分布特点,地下三层或超过地下三层的深基坑工程中承压水问题较为复杂。本文结合邻近黄浦江的两个工程实例,重点讨论其止水帷幕选型及设计问题,通过设计方案经济与合理性讨论,并进行施工可行性评价以及施工质量控制难易度分析,推荐选用不同的设计方案,为类似深基坑工程的设计提供借鉴。%The characteristics of a buried conifned aquifer (depth and thickness) in the Huangpu River area, located near Shanghai, must be determined, as the aquifer must be isolated from deep foundation pits extending to a depth of three or more lfoors. Based on two engineering examples in the Huangpu River area, this study addressed the selection and design of a waterproof barrier. Different design criteria are recommended, and accompanied by a discussion of economic factors, feasibility of construction, and analysis of the complexities of quality control, to provide a reference for engineering of similar deep foundation pits in the future.
