摘要:
根据某一沉管隧道长期运营中监测到的沉降,对一直被工程技术人员忽视的沉降问题的机理进行了分析.指出河道的淤积、潮汐的往复荷载和超载情况等都可以引起沉管隧道的沉降,提出了定期清淤、管底注浆和桩基加固的沉降控制措施和加固后管体的计算方法.并针对一个实际工程,对加固计算中地基承载力进行了分析,提出桩基加固方案,通过加固后管体的结构计算,分析了管体本身的内力和加固情况.
Abstract:
According to the settlement detected in the long-term operation of a immersed tunnel, the mechanism of settlement problems that have been neglected by engineers and technicians is analyzed. It is pointed out that the siltation of river channels, reciprocating loads and overloads of tidal tides can cause settlement of immersed tunnels, and the settlement control measures of regular dredging, pipe bottom grouting and pile foundation reinforcement and the calculation method of the reinforced pipe body are proposed. For an actual project, the bearing capacity of the foundation in the reinforcement calculation was analyzed, and the pile foundation reinforcement scheme was proposed, and the internal force and reinforcement of the pipe body itself were analyzed through the structural calculation of the reinforced pipe body.
