摘要
Abstract
In order to improve the quality of deep foundation pit engineering in soft soil area,this paper takes a high-rise building project as an example to design the reinforced large-diameter stirred pile gravity retaining wall support scheme and analyze the construction technology of the scheme,and evaluate the construction effect after construction.The results show that the elevation of pile bottom is 150 mm,the deviation of pile position is 15 mm,and the deviation of pile perpendicality is 0.5%.The pile body is complete and uniform,and the concrete strength of the pile body reaches 1.2 MPa;The maximum deformation displacement value of foundation pit retaining structure is 20 mm.All the test val-ues do not exceed the warning value and meet the requirements of the design scheme.The total engineering cost of gravity retaining wall tech-nology of reinforced large-diameter stirred pile is 82.104 million yuan,which is 3.6%higher than that of bored pile.The construction period is 60 d,which is 50%shorter than that of bored pile.The technology of reinforced large-diameter stirred pile gravity retaining wall has excel-lent social and economic benefits.关键词
