以广西某高速公路为工程背景,对炭质页岩物理力学性能进行了试验研究.炭质页岩强度随压实度的增加而增大,在水浸条件下炭质页岩的强度大大降低.运用有限元强度折减法,采用大型有限元计算软件分析了压实度及降雨对炭质页岩路堤稳定性的影响.结果表明：随着压实度的提高,路堤安全系数随之增加;降雨使路堤安全系数大幅减低,但只要路堤压实度达到93%以上,炭质页岩高填方路堤边坡不会失稳.

Taking the highway in Guangxi province as the example,the physical and mechanical performance of carbon shale is tested. The strength of carbon shale increases with the degree of compaction augment, while the strength greatly decreases under the condition of water immersion carbon shale. Using the strength reduction finite element method, the influence on compaction and rainfall for carbon shale embankment stability is analyzed by large finite element calculation software. The results show that the safety coefficient of embankment will increase, when the compaction degree increases;while it will significantly decline with rainfall. When the compaction degree is up to more than 93% ,the carbon shale highfilled embankment slope will be steady-going.
