摘　　要：针对位于杭州湾邻近海塘大堤区域的复杂条件下超大规模基坑工程施工过程中存在的困难,通过科学规范地安排基坑开挖顺序、优化降水井布置、验算大堤稳定性、采用钢板桩及三轴搅拌桩等多种保护措施,确保了基坑工程的施工质量,并为主体工程的顺利完成奠定了基础。In view of the difficulties in the construction of a large-scale foundation pit project under complex conditions adjacent to seawall levee in Hangzhou Bay,the construction quality of the foundation pit project has been ensured by arranging the excavation sequence of the foundation pit scientifically and normatively,optimizing the arrangement of dewatering wells,checking the stability of the levee,and adopting various protective measures such as steel sheet piles and triaxial mixing piles,and laid the foundation for the successful completion of the main project.
