摘要
研究目的:对新型支挡结构U型槽的结构设计进行探讨,重点解析U型槽设计中的理论计算模型、荷载、配筋以及结构施工图等关键技术问题,集中解决U型槽结构设计中的重点与难点,以为从事铁路设计的工程人员提供参考。研究结论:目前按弹性理论对U型槽结构进行分析是较为普遍而且可行的做法;分析时应合理考虑各荷载及其组合工况;宜按单筋梁进行设计,对易出现应力集中的断面应采取必要的构造措施进行加强处理;除配置受力钢筋外,还应合理的配置箍筋和分布钢筋,在控制截面需布置必要的加强钢筋;在不良地质地段U型槽可与其他工程措施并用,以满足设计要求。
Research purposes： Through the discussion on the structure design of a new type of Supporting Structure - U - Shape Groove, this paper mainly analyzes its key technical issues, such as the theoretical calculation model, loads, reinforcement and structure shop drawing for providing the solution to the focal and difficult points in the structure design of U - Shape Groove and providing some reference to the similar design. Research conclusions：Now, the general and feasible method to analyze the Structure U -Shape Groove is based on the elastic theory. All the loads including their combination behavior should be considered reasonably. The structure should be designed as the beam with single reinforcement, and some essential structure measures should be taken on the sections where there is stress concentration. Besides the stressed steel bar, the hoop, the distribution reinforcement and the reinforced steel bar for the control section are needed. In unfavorable geological area, the structure can be used with other engineering measures to meet the design requirements.
