摘要
路基沉降变形控制对高铁安全稳定地运行起到非常重要的作用。本文利用我国较早建成的武广客专大量的路基沉降观测数据,尤其是运营期间的沉降数据,分析武广客专建设期间与运营期间路基的沉降规律,重点分析了过渡段沉降对运营线路的影响,同时探讨了过渡段、路基段沉降与地基处理的关系,可为高铁建设中的沉降控制提供参考。
Subgrade settlement deformation control plays a very important role for high speed railway safe and steady operation. Based on a large amount of subgrade settlement observation data in Wuhan-Guangzhou passenger dedicated railway,especially the data during the operation period,the rules of subgrade settlement during construction and operation period in Wuhan-Guangzhou railway passenger dedicated railway were summarized,with emphasis on the influence of transition section settlement,the relationships among transition section settlement,subgrade settlement and foundation treatment. All above provide an important reference for high speed railway settlement control during construction.
