京沪高速铁路路桥过渡段沉降变形观测与分析

Observation and analysis of settlement deformation of transition between roadbed and bridge in Beijing-Shanghai high-speed railway

通过对路桥过渡段沉降变形观测数据的统计分析,得出桥台沉降与不同桩基的关系,过渡段路基沉降与不同地基处理方式、路基填筑高度的关系及桥台的高度和桩基础的深度对桥台沉降影响不大等结论,为高速铁路路桥过渡段设计、施工提供了参考。

By statistical analysis of deformation observation data in settlement between bridge and road, this article gets the relationship of the a- butment and pile foundation, relationship of transition roadbed subsidence and different ground treatment, relationship of transition roadbed sub- sidence and the roadbed const^ction height, the height of the abutment and pile foundation depth have little influence on abutment settlement. Provide a reference about design and construction of transition between roadbed and bridge of the high-speed railway.
