摘要
新形势下,随着高速铁路建设迅速发展,对无砟轨道工程质量要求越来越高。但目前施工面临的技术难点主要体现在沉降控制、刚度控制、精度控制和线型控制等方面。为有效弥补这些缺陷与不足,工程建设中应采取有效的施工技术对策,重视沉降控制,确保施工材料质量,加强无砟轨道施工刚度和精度控制,并预防裂缝出现,落实施工技术管理措施。
Under the new situation, with the rapid development of high-speed railway construction of ballastless track project quality have become increasingly demanding.But the technical difficulties currently facing the construction is mainly reflected in the settlement control, stiffness control, precision control, linear control and so on.To effectively address these shortcomings and inadequacies, construction should take effective countermeasures construction technology, emphasis on settlement control, to ensure the quality of construction materials to strengthen the non-ballasted track construction rigidity and precision control, and prevent cracks, implementation and supervision of construction measures.
