摘要
某项目位于大连港东港区,基坑面积约17 500m^2,开挖深度22.75～27.25m,采用800mm厚"两墙合一"地下连续墙作为围护体系。该项目周围环境复杂,水文地质条件特殊,给施工带来很大困难。施工过程中通过对该项目施工难点的透彻分析,制订了详尽的施工方案,优化了施工工艺,顺利完成了工程施工。
The construction project is located in the Donggang District of Dalian Port. Its foundation area is about 17 500 m^2, and excavation depth is about 22.75-27.25 m. To support the foundation, there is a 800 mm thick diaphram wall as its envelope system. The surrounding environment of project is complex, along with exceptive hydrogeological conditions, which has great difficulties to the construction. Through a thorough analysis on difficulties of this construction, we develop a detailed construction plan and ameliorate some construction proposal, so that we can complete this construction successfully.
