通过对某热连轧生产线工程的旋流井地下连续墙基坑进行结构设计分析,本文系统地阐述了在设计该类型结构时需考虑的问题,通过不同模型和软件分析,提出了解决这些问题所采用的工程设计方法。通过实际工程的验证,本文所述二维分析方法用于旋流井地下连续墙基坑的设计是可行的。本文还阐述了地下连续墙基坑支护结构某些复杂节点的做法,可供有关工程技术人员参考。 Through the structural design and analysis of the foundation pit of the continuous wall of the spiral hole in a hot continuous rolling production line project, this paper systematically expounds the issues to be considered in the design of this type of structure. Through different models and software analysis, it is proposed to solve these problems The engineering design method used. Through the actual engineering verification, the two-dimensional analysis method described in this paper is feasible for the design of the foundation pit of the continuous diaphragm wall of the cyclone well. This paper also elaborates the practice of some complex joints of foundation pit supporting structure of underground continuous wall, which can be referenced by relevant engineering technicians.
