摘要
琼库什台冰碛物阶地崩塌位于特克斯县南部,为琼库什台河二级阶地,阶地由冰碛物构成,长约850m,高差在5~80m,走向约225°,坡度在25°~45°。坡体中上部坚硬土体及漂石在降雨冲刷、风化、地震以及动物活动扰动作用下会进一步被剥离,使之坡度(悬空)逐渐变大,当前缘临空向上力不足以支撑其重力时失稳崩落,形成崩塌灾害。根据冰碛物崩塌的基本特征,分析研究了琼库什台冰碛物阶地崩塌灾害的形成条件及机理,对其危害影响做了研究分析,为崩塌灾害的防治提出了治理思路分析。
Joankush glacial till machine terrace collapse is located in the south of Tex coun- ty, the second terrace for Joan kush river terraces formed by glacial till, about 850 meters long; elevation difference in 5--80 meters, to about 225 degrees, slope in 25 to 45 degrees. Slope of the upper hard boulders in rainfall erosion, weathering, and soil disturbance under the action of earthquake and animal activity further, stripped, slope （suspended） increases gradually, the current international airport edge upward force strong enough to support its gravitational instability of the caving, formation collapse disasters. According to the basic characteristics of glacial till collapse, analyzed the Joan kush glacial till machine terrace col- lapse disaster formation conditions and mechanism of the influence to the harm done research and analysis, proposes the governance for disaster prevention and control of the collapse a- nalysis.
