高速铁路对线路路基、桥梁、隧道等结构物的稳定性、牢固可靠性要求十分严格。为了保证客运专线路基足够强度、刚度、长期稳定性及耐久性、变形均匀协调性。以武广客运专线路基工程中地基加固施工为例,结合沿线实际地质状况,对注浆加固、桩基加固、强夯及冲击压实、基底换填、检测控制等方面进行了阐述。 High-speed railway on the roadbed, bridges, tunnels and other structures of the stability, reliability requirements are very strict. In order to ensure sufficient strength, stiffness, long-term stability and durability of passenger dedicated railway embankment, uniform deformation and coordination. Taking reinforced construction of subgrade in Wuhan-Guangzhou passenger dedicated line as an example, this paper elaborates the aspects of grouting reinforcement, pile foundation reinforcement, dynamic compaction, impact compaction, replacement of foundation, and test control based on the actual geological conditions along the line.
