摘要:
无砟轨道采用混凝土道床来替代传统的碎石道床,具有平顺性好、结构稳定、维护成本低等优点,在高速铁路和重载铁路中得到广泛应用。裂缝是无砟轨道混凝土结构中常见的病害。为有效整治无砟轨道结构的裂纹病害,需要对轨道结裂纹成因进行分析。本文研究了某铁路现浇无砟轨道混凝土裂缝成因,旨在揭示无砟轨道道床板裂缝的形成机制,为其后续维护和改进提供科学依据。
Abstract:
Ballastless tracks, which utilize concrete track beds to replace traditional ballast track beds, exhibit advantages such as good smoothness, structural stability, and low maintenance costs. They have been widely adopted in high-speed railways and heavy-haul railways. Cracks are a common defect in the concrete structures of ballastless tracks. To effectively treat the crack defects in ballastless track structures, it is necessary to analyze the causes of track joint cracks. This paper studied the causes of cracks in cast-in-situ concrete ballastless tracks on a railway. The objective is to uncover the formation mechanisms of cracks in the ballastless track bed plate and provide a scientific basis for subsequent maintenance and improvement.
