摘要
基坑支护结构属于临时性的工程,用最节省的方案安全地完成支护,是基坑支护设计者的根本目标。本文以广州地区的某基坑工程为例,根据该基坑周围各边不同的环境条件,确定了不同的基坑安全等级,并分别采用了桩锚支护和复合土钉墙两种支护方案,同时对地下水的控制采取了合理的方法,提出了关键的施工要点,在复杂的现场条件下通过尽量少的投资,保证了基坑本身及周围已有建筑物、市政道路及管线的安全。所得结论对实际工程有一定的指导意义。
Supporting structure of deep foundation pit is a kind of temporary project. How to make a safety and the most economical design is the fundamental goal of all the designers. In this thesis, an engineering example of Guangzhou is introduced. According to the different environmental conditions of the different pit sides, different structural safety grade is defined, moreover, pile-anchor retaining and composite soil-nailing wall retaining are se- lected as the supporting structure of this deep foundation pit at the same time. This thesis also introduces a proper method of groundwater control and the key points in the process of construction. With this considerate design, the deep foundation pit itself, the buildings and roads around the pit are all well protected with the least investment. The conclusions have a certain significance for actual engineering.
