连续墙基础在钱塘江出江口门应用刍议——以扩大杭嘉湖南排杭州三堡排涝工程前期准备工程为例

Discussion on Application of Continuous Wall Foundation in Qiantang River Estuary Gate——Example of Prophase Preparation Engineering in Expanded Hangjiahu Nanpai Hangzhou Sanbao Drainage Project

本文针对扩大杭嘉湖南排杭州三堡排涝工程前期准备工程因安全稳定需要设置相应工程措施的情况,分析了单孔引(排)水箱涵基础处理的主要影响因素。在初选连续墙基础方案后,从交叉衔接处理、稳定验算、有关技术要求、施工处理方案和其他保障措施等方面进行了方案优化。

Corresponding project measures should be set for Prophase Preparation Engineering in Expanded Hangjiahu Nanpai Hangzhou Sanbao Drainage Project due to safety and stability. Main influence factors of single hole division （drainage） water culvert foundation treatment is analyzed aiming at the above condition in the paper. The programs are optimized in cross convergence treatment, stability checking, related technical requirements, construction processing program, other security measures and other aspects after continuous wall foundation programs are selected initially.
