ABSTRACT
ABSTRACT: According to results of centrifugal model tests and model tests, the influence of the soil properties, pile types and layout, foundation size on the anti-bursting stability of foundation pit were studied. It was shown that the mainly failure modes of impermeable layers in Shanghai were overall heaving and surface boiling. Water and sand inrushing in contact between soils and underground structures was mainly occurred when the existence of pile in foundation pit. Foundation size had a significant effect on the anti-bursting stability of foundation pit.
