摘要

采用模型试验方法，对不同颗粒级配、不同含水量软岩路基在不同竖向准静荷载作用下的沉降和应力的分布规律进行了研究，得出了一定的颗粒级配与含水量软岩填筑的路堤，通过压实可以满足路基设计规范技术要求，并通过两种填料级配和含水量情况下的填筑路堤进行较高荷载试验研究，分析了其变形破坏特征。研究成果可充分利用铁路沿线软岩资源、节省工程投资、少占耕地农田、保护环境，社会和经济同时受益。

Abstract

Model test method is used to analyze the distributing characteristics of stress and settlement with different grain gradations

series

water contents and vertical quasi static loads in soft rock roadbed. It is concluded that roadbed stuffed by soft rock with definite grain gradation and water content can satisfy technical requirement of roadbed design criterion. High load test is used to analyze deformation and destroy characteristics of soft rock roadbed with two kinds of grain gradations and water contents. The results show that using the method of the soft rock roadbed can make full use of soft rock resources along the railway line

occupy less cropland

protect environment and make considerable social and economic benefits.
