摘要:
目前,部分海外项目采用了与我国标准轨距不同的宽轨距,其具有枕中负弯矩较大的结构受力特点,与我国传统的轨枕设计方法不同。本文研究了欧洲标准宽轨距有砟轨道混凝土轨枕设计方法,并以某海外项目1 676 mm宽轨距有砟轨道预应力混凝土轨枕设计为例,通过设计检算和室内试验验证了设计方法的可行性,同时给出了轨枕动压力、特征弯矩计算与钢筋预应力损失的推荐计算方法,研究结论可为类似海外项目轨枕设计提供借鉴与参考。
Abstract:
At present, some overseas projects have adopted a broad gauge that is different from the standard gauge in China, and it has the structural stress characteristic of large negative bending moment in the sleeper, which is different from the traditional sleeper design method in China. In this paper, the design method of concrete sleepers for the ballasted track with European standard broad gauge is studied. Taking the design of prestressed concrete sleepers for the ballasted track with 1 676 mm broad gauge in an overseas project as an example, the feasibility of the design method is verified by design check and laboratory test. At the same time, the recommended calculation methods of sleeper dynamic pressure, characteristic bending moment calculation and prestress loss of reinforcement are given. The conclusions can provide a reference for the sleeper design of similar overseas projects.
