摘要
研究目的:针对客运专线无砟轨道路基沉降控制工程面临的新问题,探讨"预沉降法"的可行性。研究结果:该工法可减少工后沉降和不均匀沉降,满足无砟轨道铁路路基沉降变形控制的要求,且可达到过渡段路基工后"零沉降"的目标。
Research purposes:Aiming at the new problem of passenger dedicated railway ballastless track roadbed decline control project,this paper explored the feasibility of "a method of prepare to decline" Research results:The new method can reduce the post-construction settlement and the foundation asymmetry to decline,satisfy the request of both passenger dedicated railway ballastless track roadbed decline control project and "zero post-construction settlement" at transition zone between roadbed and bridge.
