Abstract


Deep excavation engineering is increasingly widespread application in high-rise buildings , underground engineering and municipal engineering . In -depth analysis of deep excavation engineering research at home and abroad based on theoretical analysis and numerical simulation methods to study the law of force and deformation of retaining structure in deep excavation engineering ; combined with engineering practice , and analyzes the cross deep foundation pit in space effect ( positive angle effect ) and the impact of different constitutive model . The main work and conclusions are as follows: ( 1 ) summarizes the analysis of the history of the development of the deep excavation engineering and research status , and on this basis , combined with a deep foundation engineering and design and construction shortcomings of deep Excavations trends ; (2) describes the deformation behavior of the retaining structure and the surrounding formations deep excavation engineering analysis of deep foundation pit deformation mechanism , summarized the design of deep foundation commonly used theories and methods of computation ; (3) to Qingdao metro-North station line 1,3 king complex deep foundation engineering background, using the finite difference method, the the FLAC numerical calculation model . Using the above model , double - row piles retaining structure design parameters of its Deformation of research can provide a reference for similar projects ; (4 ) the cause of yang Qingdao Metro-North station cross -type pit excavation angle effect , the first analysis of the the pit angle on Foundation Pit Deformation , after the establishment of a three-dimensional numerical model to consider the synergy of the entire supporting structure , the internal forces and deformation of the excavation process , comparing different constitutive model pit numerical analysis of the applicability and soil rebound coefficient results .
