Abstract:The top-down constructing method was used in a 14.05～16.6m deep foundation pit engineering in Hangzhou. The deep pit is surrounded by many buildings and the requirements for protection of surrounding environment are quite strict. The design course of foundation pit was introduced. The top-down method was used in the design scheme including the design of diaphragm wall, the horizontal and vertical system in the foundation pit. It is shown that the top-down method associated with monitoring technology can ensure the safety of the surrounding environment. Some useful conclusions are obtained through the analysis of measured results.
Keywords:deep excavation; top-down method; monitoring
