武广线高边坡陡坡地段桩板结构路基的设计理论探讨

Theoretical Exploration on Design of Pile-plate Structure Subgrade in Steep Slope Section of High Side Slope on Wuchang-Guangzhou Railway Passenger Dedicated Line

研究目的:桩板结构路基是土质路基上无砟轨道的一种新型结构形式,本文结合武广线桩板结构路基的设计,初步探讨桩板结构路基的设计方法,希望能够为桩板结构路基的设计及应用提供参考。研究结果:桩板结构路基是高边坡陡坡地段地基加固的一种有效形式,通过计算,承载板挠度、桩基础承载力及其变形均满足了无砟轨道的控制指标要求,是桩板结构路基应用范围的一个新的突破。

Research purposes:The pile-plate structure subgrade is a new type structure of subgrade of ballstless track on soil subgrade.In combination with the design of pile-plate structure subgrade of Wuchang-Guangzhou Passenger Dedicated Line,the primary exploration is made in this paper on the design method of pile-plate structure subgrade for the purposes of providing the references to the design and application of pile-plate structure subgrade. Research results:The pile-plate structure subgrade is an effective w...
