Abstract: It focuses on design, construct and detection of deep foundation pit during sand area under complicated environment in Binjiang district, Hangzhou. Based on many factors such as depth of foundation pit and surrounding environment and soil stratigraphy and deformation control, support structure combined soil mixing wall (SMW) pile and a layer of concrete support was adopted and some measures of water lever control such as waterstop, depressing water and drainage water was adopted. Thus, the safe and economical and deformation control results were achieved. 

Keywords: sand area; complicated environment; deep foundation pit
