【摘要】：滑坡分類(lèi)研究一直是滑坡研究的基礎(chǔ)和重點(diǎn)。通過(guò)對(duì)山西煤礦區(qū)滑坡災(zāi)害的工程實(shí)踐和大量的調(diào)查統(tǒng)計(jì)分析,根據(jù)滑坡地層結(jié)構(gòu)、巖性特征、誘發(fā)機(jī)制及運(yùn)動(dòng)特征等因素將山西煤礦區(qū)滑坡歸結(jié)為5種類(lèi)型:順基巖面推移—滑動(dòng)型黃土滑坡;蠕滑—擠出型黃土滑坡;水浸溜滑型黃土滑坡;煤層自燃傾覆—拉裂滑移型巖質(zhì)滑坡;受節(jié)理控制的蠕滑—張裂型巖質(zhì)滑坡。研究結(jié)果發(fā)現(xiàn):黃土滑坡滑帶土一般為松散土層,巖質(zhì)滑坡的滑面為軟弱結(jié)構(gòu)面(多為泥巖薄層)或煤線;除溜滑型黃土滑坡滑動(dòng)速度較快外,其他為低速滑坡,其典型特點(diǎn)是歷時(shí)長(zhǎng),滑距短,致災(zāi)范圍小,但滑坡推力大,破壞力強(qiáng),往往造成更大損失。該研究進(jìn)一步細(xì)化了滑坡分類(lèi)的內(nèi)容,其成果可對(duì)山西礦區(qū)及類(lèi)似滑坡地質(zhì)災(zāi)害的防治提供指導(dǎo)。
[Abstract]:Landslide classification research has been the basis and focus of landslide research. Based on the engineering practice of landslide disaster in Shanxi coal mine area and a large number of investigations and statistics, according to the structure and lithologic characteristics of landslide, The induced mechanism and motion characteristics of the landslide in Shanxi coal mine area are divided into five types: the bedded sliding loess landslide along the bedrock surface, the creep slide extruding loess landslide, the water leaching slide slip loess landslide; Coal seam spontaneous combustion capsizing-tension slip type rock landslide; joint-controlled creep-tension type rock landslide. The results show that the soil in the loess landslide slide zone is generally loose soil layer, and the slip surface of the rock landslide is weak structural plane (mostly mudstone thin layer) or coal line, except the slip loess landslide sliding speed is fast, the others are low speed landslide, Its typical characteristics are long calendar, short slip distance, small range of disasters, but the landslide has large thrust and strong destructive power, which often results in greater losses. The research further refines the content of landslide classification, and the results can provide guidance for the prevention and treatment of geological hazards of Shanxi mining area and similar landslide.
