【摘要】 以肖家洼煤矿变电站东侧滑坡为研究对象,分析了滑坡形成机理,研究机械成孔抗滑桩技术并成功应用该技术,得出:肖家洼煤矿变电站东侧滑坡由上部粉土与下部粉质黏土交界处受渗水浸泡、软化,抗剪强度降低,诱发滑坡的形成;滑坡为推移式滑坡,滑坡体积约30 000 m3,中型滑坡;机械成孔抗滑桩施工设备占地小、简便、易操作,施工过程安全、高效;采用机械成孔抗滑桩治理后,滑坡累计变形量增加逐渐变缓,变形趋势收敛明显,滑坡变形得到有效控制,坡体稳定,效果明显。更多还原

【Abstract】 The landslide on the east side of the substation in Xiaojiawa coal mine was studied, the mechanism of landslide formation was researched on. The mechanical hole-forming anti-slide pile technology was studied and applied successfully. The landslide on the east side of the substation in Xiaojiawa coal mine was formed by the junction of upper silt soil and lower silt clay, which was soaked and softened by seepage water, and the shear strength was reduced. The landslide was a sliding type,with a volume of about 30 000 m3. It was a medium landslide. The construction equipment of mechanical pore-forming anti-slide pile was small, simple, easy to operate, and the construction process was safe and efficient. After the mechanical hole-forming anti-slide pile was used, the accumulated deformation of landslide increased gradually and gradually became slow, and the deformation trend converged obviously. The landslide deformation was effectively controlled, and the slope was stable with obvious effect.更多还原
