【摘要】 水帘洞煤矿工业场地西侧黄土高边坡为老滑坡的后壁,在边坡的脚下有老滑坡体残留物。地表水沿黄土垂直节理、裂隙下渗,逐渐在边坡的顶部形成落水洞;边坡还受黄土层理、倾角(5°~10°)和古土壤层位置的控制,地表水下渗至古土壤层,古土壤层是良好的隔水层,加上黄土层理倾向沟谷,在古土壤层面位置(半山腰)易形成与边坡顶部落水洞贯通的落水洞出口。受长期降水或短期强降水的影响,导致边坡失稳。更多还原

【Abstract】 The loess high-slope on western end of Shui Lian Dong colliery is an old landslide debris back-wall. There is an old landslide debris depost in the slope bottom. Surface water can infiltrate into the slope through loess uprightness joints and cranny. The groundwater flow gradually causes the formation of water cavities in the upper slope region. The slope further has loess stratification, obliquity (from 5°to 10°) and paleosol’s place. Surface water infiltrate into paleosol and induce water cavity exit with the top water cavity transfixion. The paleosol ideally prevents water. The loess stratification leans to ravine. The slope is unstable and will fail under the action of precipitations.更多还原
