Fuzzy Reliability Analysis of Resistant Heave Stability for SMW Exterior-Protected Structure Deep Foundation Pit
With the development of deep foundation pit engineering, SMW exterior-protected structure is used widely day by day in foundation pit engineering. In order to study on the resistant heave stability of SMW retaining structure deep foundation pit. By using finite element analysis method, a non-linear finite element model, which analyzes the stability of resistant heave for deep foundation pit based on deformation, is established. Considering the influencing factors of deformation against upheaval of deep foundation pit exist maximal fuzziness and randomness, based on deformation, the δ-δ ultimate limit state model is built up to reflect the failure process of deep foundation pit. In the course of analysis, the fuzzy mathematics and reliability analysis method is used to set up fuzzy reliability method to analyze the resistant heave stability of deep foundation pit. The study shows that ABAQUS has powerful capacity to analyze the contract problems in geotechnical engineering, the resistant heave failure ultimate limit state model based on deformation of deep foundation pit can effectively analyze stability of deep foundation pit, and the study can provide valuable reference for the stability analysis for foundation pit.
