红砂岩路基填筑加固措施研究

针对红砂岩具有强度低、软化系数小、易崩解、且崩解后表现出活性的特点，分别对红砂岩路基填筑加固的碾压及冲击补压、封闭断面、水平夹层和水泥改良等几种加固措施进行了研究，从而为红砂岩作为高速铁路基床以下路堤填料的设计与施工积累经验。

On research of intensifying measures in roadbed filling of red sandstone

Aimming at the characteristics of the red sandstone, that is,low intensity,small soften coefficient,easy disintegration,and the activities after the disintegration,the paper researches some intensifying measures,such as the rolling of the filling and intensifying the red sandstone pavement,the push-pull supplement pressure,the closed section,the level dissection,the cement-improvement,so as to accumulate experience for the design and construction of the express railway with the red sandstone as the embankme...
