针对南昌绿地中央广场项目所处红谷滩区域复杂的工程水文地质情况,以及项目内部相邻分区地块间的复杂的相互关系及环境问题,通过引入由TRD工法所构建的等厚度水泥土搅拌墙等关键技术,并结合以"中心岛"方案为主、内支撑方案为辅、多种支护结构相结合的总体方案,有效地进行了复杂环境下多种支护结构相结合的基坑工程设计与实践。
In the light of geological conditions of Nanchang Greenland Center Plaza, staged implementation of partitioned neighboring excavations and impact on the surrounding environment, some key technologies are described, such as the constant thickness steel cement-soil wall constructed by TRD (trench cutting re-mixing deep wall) method. The general scheme for D area, that is, the 'center island' method and the combination of various support systems is introduced. The design method for excavation engineering with the combination of various supporting systems under complex environment is discussed.
