摘要
结合东北严寒地区高速铁路路基及桥梁冬季施工难题,为保证工程质量,从原材料的选择、填料保温运输、填筑施工与检测等方面介绍了路基冬季施工应采取的主要工程技术措施,论述了桥梁混凝土、桩基及承台,预制梁、现浇梁和悬灌连续梁等相关工程过程控制措施,分析了相关工程冬季施工的可行性,为东北严寒地区高速铁路路基和桥梁施工提供科学依据。
With the difficulties in the winter construction of the roadbed and bridges of the high-speed railways in the cold regions of the Northeast of China taken into account,to ensure the quality of the projects,the main engineering and technical measures to be taken in winter construction are dealt with in the paper,from the angles of the right choice of raw materials,the temperature-maintaining and transportation of the filling material,filling construction and inspection,etc.,with greater stress placed on the construction processes and control measures of the bridge concrete,the pile foundation and caps,pre-cast beams,cast-in-place beams and the suspended pouring of the continuous beams.The feasibility of the construction of the projects in winter is also analyzed.It may serve as scientific grounds for the construction of roadbeds and bridges of high-speed railways in the cold areas of the Northeast of China.
