Abstract：A foundation pit project of a large residential underground garage in Shanghai as well as the warning treatments for its dangerous situations is taken as an example. The deformation characteristics and danger causes of the excavation in deep and soft soil areas are analyzed and discussed, and targeted suggestion is proposed. Finally, the emergency experience and lessons were summarized. It will provide beneficial reference for the design and construction of supporting structures for foundation pits, accident prevention and warning settlement of similar projects.
