摘要
结合实际工程案例,阐述了地铁工程中的盾构机反力架设计存在的问题和矛盾,重点分析架体受力状态下产生的附加弯矩和附加力偶如何消除的难题,从而提出反力架制作和安装的控制要点,可为盾构机反力架的质量控制提供一定的参考。
Combined with the actual project case, the problems and contradictions in the main design of the reaction frame of the shield tunneling machine in metro project are expounded in this paper. The problems of additional bending moment and the additional force couple relief generated in the stressed state of the frame body are analyzed emphatically. As a result, the key control points of fabrication and installation of reaction frame are presented, which can provide reference for quality control of shield machine reaction frame.
