Abstract The Zhenjiang Gangzixia housing placement project connects that Kuangji road to the west and borders Hongheqiao road to the west with a convenient transportation. The construction of this project is similar to the underground garage, the foundation pit area is about 5757m^2, and the excavation depth of foundation pit is 10.35m and 9.55m in the other sides. The graduation project for the foundation pit engineering geology, the surrounding environment, foundation pit size and other conditions, to determine the safety and reliability of the supporting program. Main work includes: (1) introduce the common foundation pit supporting form, and compare the advantages and disadvantages of the foundation pit form. (2) combined with the characteristics of the foundation pit of this project, the supporting scheme is defined as the bored pile + two concrete support. (3) select two typical sections of the support structure design, including the calculation of soil pressure, the pressure of the pile, the overall stability of foundation pit, uplift stability, etc.. (4) using Lizheng software (version 7) computer check. (5) according to the selection of the support structure, the preparation of construction technology requirements. (6) in view of the surrounding environmental protection requirements, determine the foundation pit monitoring requirements and monitoring alarm value. (7) construction plan, including the surrounding environment, supporting layout, structure supporting structure and profile detail.
Keywords:Excavation; Bored piles; Reinforcd concrete support.
