摘要
客运专线最重要的就是保证行车的高平顺性,路基是保持线路平顺性的基础,但路基沉降变形复杂,路基应具有较大的刚度、连续性和均匀性。施工中应加强地基加固施工质量、做好地质核查、保证路基填筑层的质量控制、控制路基过渡段的质量、重视路基沉降观测、做好路基防排水和路基检测等工作。
The most important thing of passenger special line is guarantee the higher stability. The railway bed is the base of guarantee the stability. But the railway bed has complicated deformation. The railway bed should have higher stiffness, continuity and uniformity. Enhance the construction quality of base strengthening, to do geological exploration better, guarantee the quality control of filling layer of the base, control the quality of base transition segment, the base settlement observation, base waterproof and water prevention are the key points of the base stable for a long time. It is the vitals of observation work to guarantee the base quality.
