摘要
贵州省龙里县地处云贵高原东部、黔中腹地,属于喀斯特地区,地形地貌,地质条件复杂,是地质灾害的多发区。全县地质灾害威胁居民较多,危害性较大,具有分布不均匀性,在一定小范围成群集聚出现的特点。目前全县地质灾害隐患点共29处,其中崩塌11处,滑坡6处,地面塌陷9处,不稳定斜坡3处,崩塌是主要的地质灾害类型。共威胁701户3127人的生命安全,以及3条公路,可能造成的潜在经济损失为5123万元;地质灾害隐患点均处于不稳定状态和欠稳定状态。影响地质灾害的因素有地形地貌、岩土体工程地质、气象水文、采矿工程等,其中地形地貌、岩土体工程地质和气象水文的影响较大。
Longli County of Guizhou Province is located in the eastern part of Yunnan Guizhou Plateau and the hinterland of Central Guizhou Province.It is a karst area with complex landform and geological conditions,which is a frequent area of geological disasters.The geological disasters in the whole county are more threatening to the residents,more harmful,with the characteristics of uneven distribution and clustering in a small area.At present,there are 29 potential geological hazards in the county,including 11 collapses,6 landslides,9 ground collapses and 3 unstable slopes.Collapses are the main types of geological hazards.The potential economic loss of 3127 people in 701 households and 3 highways is 51.23 million yuan,and the hidden danger points of geological disasters are in unstable and unstable state.The factors influencing geological disasters include topography,engineering geology of rock and soil mass,meteorology and hydrology,mining engineering,etc.
