泥岩形成环境与其填筑路基工程性质的关系
|
摘要
用湘南湖相泥岩与黔西南浅海相泥岩的物理性质试验结果以及它们填筑路基的经验，分析了泥岩的沉积环境与其工程性质之间的关系．得出：内陆湖相泥岩由于碎屑物及钙质物含量高，水稳定性好，是良好的路基填料；浅海相泥岩由于粘土矿物含量比较高，水稳定性较差，不宜用来填筑易受水浸害处的路基．
おhe authors analyse the relationship between the engineering character of filling roadbed with these mudstones and their deposit environment,based on the physical character test results and their experimence in filling roadbed.There are two kinds of mudstone:one belongs to lacustrine in the south of Hunan province,and the other belongs the shallow marrine in the south west of Gueizhou province.The conclustion is that the lacustrine mudstone is a better material for filling roadbed,because of the high content of clastic and calcium and because,it has better stability when water acts on it.Because the clay minerals content in the shallow marrine is high,it has worse stability when water acts on it.It should not be used to fill the roadbed where the foundation is lowr and it is easy to be acted by water.
