复合含水层地区深基坑减压降水方案优化设计

摘要

In light of decompression technology difficulty in deep foundation construction process in composite aquifer region,taking Fengxian section foundation of corridor crossing river engineering of Hongmei south road-Jinhai road in Shanghai city as the example,it proposes combination method of pumping test and three-dimensional numerical simulation method,so as to achieve the goal of decompression scheme optimization design.%针对复合含水层地区深基坑施工过程中降承压水的技术难题,以上海市虹梅南路—金海路通道越江段工程奉贤段深基坑为例,提出采用抽水试验与三维数值模拟方法相结合的方式,达到减压降水方案最优化设计的目的。
