摘要基坑工程是一门综合性很强的学科，它包括结构的强度和稳定性的计算。同时又受到地质及水文条件等环境因素的控制。另一方面，基坑支护结构是临时性构筑物，经济因素也是主导其合理性的重要方面。如何设计出安全、合理、可行的基坑方案，已然成为建筑工程界的共同话题。51301
本文主要是对扬中城东安置点1#地库基坑进行设计。首先运用郎肯理论计算土压力，接着根据土压力进行支撑轴力以及最大弯矩计算，之后进行配筋计算。再使用理正软件进行校核，最后给出施工图。

Abstract Foundation pit engineering is a highly integrated discipline, which includes the calculation of structure strength and stability. At the same time, it is also controled by the environmental factors such as geological and hydrological conditions. On the other hand, the retaining structure of foundation pit is a temporary structure, so economic factors are also important aspects of leading its rationality. How to design a safe, reasonable, and feasible foundation pit project has become a common topic in the construction field.
This article is mainly on the Yangzhong Chengdong placement 1# library Foundation Pit Support Design. Firstly, Rankine theory was used to calculate the earth pressure. Secondly, based on the earth pressure, the supporting axial force and maximum bending moment were calculated. Thirdly, the reinforcement calculation was conducted. Forthly, the manual calculation results were verificate by the Lizheng software. Lastly, the construction drawings were given.
