客运专线施工过程中的沉降观测和科学合理的沉降变形分析是客运专线铁路建设质量的关键环节,文中采用海南东环铁路客运专线线下结构沉降观测数据,选择工程上比较成熟的三点法、双曲线法、Asoka法推算工后沉降的发展趋势,可指导客运专线铁路无砟轨道区段线下结构的沉降变形观测与分析评估工作。
Subsidence observation and scientific and reasonable settlement deformation analysis during the construction of passenger dedicated railway line are the key links of railway construction quality of Passenger Dedicated Line. By using the data of subsidence structure observation of Hainan Dong-Hailun Railway Passenger Dedicated Line, this paper selects the more mature three-point method, Hyperbolic method and Asoka method to predict the post-construction settlement trend, it can guide the observation and analysis of settlement deformation of the line structure under the ballastless track section of passenger dedicated railway line.
