临海超深地下连续墙施工质量控制措施

某工程地下连续墙设计为深基坑围护墙和建筑物承重墙两墙合一,该场地毗邻海岸,海水与场地地下水有联系,对地下连续墙防渗性能要求较高。本文针对该工程地质差、地下水位高、地形复杂、地下障碍物多的特点,对地下连续墙施工的难点、质量控制措施及采取的对策进行了论述。

Control Measures of Construction Quality for Super Deep Underground Continuous Wall at the Coast

The underground continuous wall of a project combined two functions of the enclosure wall for deep foundation pit and bearing wall for the building together.The site is adjacent to the coast.The sea water and groundwater of the site have relationship of replenishing each other.There is a higher requirement of leakage prevention for the underground continuous wall.The paper discussed the difficult points of underground continuous wall construction,quality control measures and countermeasures considering the poor engineering geological conditions,the higher underground water level,complex topography,multi underground obstructions.
