摘要

针对武广客运铁路专线沿线遇到的大量软质千枚状板岩和泥质粉砂岩

在分析风化软岩基本矿物成分、耐崩解性的基础上

结合风化软岩岩块力学强度和击实试验结果

初步判定了风化软岩填筑路基的可行性

同时提出了软岩填筑路基可行性的初步判定方法。

Abstract

On the basis of field survey of slate phyllite and siltstone along Wu-Guang Railway

the mineral components and the properties of enduring collapse are discussed. Then

combining the strength of weathered soft rock and the results of compaction test

the feasibility of filled subgrade with weathered soft rock are judged. Furthermore

the judging principle and method of feasibility of filled subgrade with weathered soft rock are set up.
