杭州百大绿城庆春广场项目位于繁华的闹市区，东靠银泰商场和庆春广场，西北角为欧亚达广场，西侧紧贴多幢3层民房，周边环境非常复杂；同时，该工程基坑开挖深度普遍达到18.7m和19.7m，局部电梯井等深坑开挖深度达22.45m，开挖期间受到承压水的影响，需对承压水进行处理。围护设计采用地下连续墙结合三道水平内支撑的围护形式，同时对西侧靠近民房的位置采取了针对性的加强措施；另外，对于局部深坑，没有按照常规的设减压井的方式来处理承压水，而是采取了局部加固措施来保证抗承压水的稳定性。通过以上措施，有效地确保了基坑开挖的顺利进行和周边环境的安全。

Baida-Greentown Qingchun square project is located in bustling downtown of Hangzhou, on the east side to Intime mal and Qingchun square, southeast to Ayd mal , on the west side close to civil houses, the surrounding environment is complex. At the same time, the pit depth general y reach 18.7m and 19.7m, elevator pit depth reach 22.45m, measures need to be taken against the confined water during excavation. Pit supporting design uses a combination of diaphragm wal with 3 lateral bracing, and targeted measures have been taken to improve civil houses safety on the west side;the project substitute foundation reinforcement for relief wel system to deal with the confined water.
