Abstract:

Traditional supporting design of rock foundation pit often ignores the interaction between rock foundation pit and supporting structure as well as the effects of adjacent buildings on the supporting structure and the stability of foundation pit. Combining with practical engineering, adopting finite element program of PLAXIS, the stability and the deformation of rock foundation pit, rock lateral pressure, the influence of excavation on the adjacent buildings and the optimization design of supporting structure are analyzed respectively through finite element strength reduction method and finite element method. According to the structural design regulations of high building and design standards of foundations, the deformation control conditions of adjacent buildings are put forward, which are taken as the controlling basis, the calculation of rock lateral pressure and the design of supporting structure of rock foundation pit are carried out according to the limit values of deformation. This method can save the construction cost and cut down the construction period effectively.

Key words: adjacent buildings, rock foundation pit, finite elements, supporting structure, optimization design
