The ICD Brookfield Place development in Dubai comprises a 290 m tall tower with a seven-level basement (the deepest in Dubai at the time of construction). A five-level basement, with temporary anchored retaining walls along three sides, was previously constructed on the site along with all the foundation piles for the intended structure. The basement was later backfilled when construction ceased in 2009. The previous basement provided considerable constraints to construction of the new basement. Particular challenges included deepening of the basement, the construction of new deeper temporary retaining walls, pile reuse and construction in close proximity to adjacent structures. This paper describes how the constraints were assessed and how a basement construction strategy was developed to overcome them.

规划在先前保留的挖掘现场建造深地下室

迪拜的 ICD Brookfield Place 开发项目包括一座 290 m 高的塔楼和一个七层地下室（建造时迪拜最深的地下室）。一个五层地下室，三边都有临时锚定挡土墙，之前在现场建造了预期结构的所有基础桩。地下室后来在 2009 年停止施工时被回填。以前的地下室对新地下室的建设造成了很大的限制。特别的挑战包括地下室的深化、建造新的更深的临时挡土墙、桩的再利用和靠近相邻结构的施工。本文描述了如何评估约束以及如何制定地下室建设策略来克服它们。
