特殊条件下地下连续墙的施工技术

Construction techniques of diaphragms under special conditions

介绍上海铁路南站特殊地段所采用的地下墙墙顶超低施工技术。该施工技术具有一定优势,但是目前尚存在一些问题。在施工过程中,运用回填技术对土壁进行保护,保证了施工期间的安全,同时为今后类似工程的施工积累了宝贵的经验。

Application of ultra-low construction techniques of diaphragms in special area in Shanghai South Railway Station was introduced. The construction techniques have advantages, but also have some problems now, During the construction, backfilling was employed to reinforce the soil wall, and it ensured the construction safety and accumulated the successful experiences for engineering.
