| 摘 要： | 露天矿开采过程中边坡变形破裂过程一直是岩土工程领域研究的难点,尤其考虑含火烧煤层露天矿开采过程中的边坡稳定使得研究问题更加复杂。采用FEPG数值模拟的研究方法,对露天矿某边坡KT3剖面进行了破裂过程分析,得到了含火烧煤层露天矿边坡变形破裂规律,研究结果表明,边坡火烧砂岩的顶部首先出现拉张裂缝,边坡以压剪破坏为主,压剪破坏又促使拉张破坏,二者相互影响,最终导致边坡发生失稳破坏。

| Abstract: | The slope deformation and fracture of the open-pit mining process has been the difficulty of research in the field of geotechnical engineering,especially containing the fire coal seams in open-pit mining process.The slope failure process of the openpit KT3 profile is analyzed by adopting FEPG numerical simulation method.The law of open pit slope deformation and fracture containing the fire coal is received.The results show that tensile fractures and shear failure appeared at the top of the slope at first,the two force influence each other,and eventually leads to slope instability destruction. |
