| 摘 要： | 湿陷性黄土地基上的无砟轨道,其路基的工后沉降控制是时速300～350公里客运专线建设面临的一大课题。由于湿陷性黄土工程性质的复杂性,必须对黄土地基采取必要的加固措施,以消除其湿陷性;对于用改良土填筑的路基本体、基床底层应确定严格的施工工艺和方法,确保压实质量和标准;同时,对路基沉降进行科学合理的监测,利用曲线回归方法预测工后沉降量。路基工后沉降控制是一项复杂的系统工程。

| Abstract: | A great task for construction of 300-350km/h passenger transport line is to control loess subgrade settled behind filled later of unballast tracks on the collapsible loess foundation.Because of complexity of the collapsible loess engineering properties,necessary reinforcing measures must be taken to remove its collapsibility for loess foundation;strict construction technique and methods should be determined by body and bottom layer of subgrade bed filled with improved soil to ensure compaction quality and s... |
