【摘要】 赵子秀山变形体位于华蓥市西北部,变形体一旦失稳将直接对华蓥市造成威胁。本文从斜坡地质结构、变形破裂特征、地貌演化及人类工程活动(采煤)入手,结合数值模拟的方法研究变形体的变形机制。研究表明变形体的形成是下部含煤层的中倾角反向层状结构斜坡在河谷下切过程中发生倾倒-拉裂变形所致,同时,后期的采煤活动对拉裂变形的发展有较大影响。更多还原

【Abstract】 The Zhaozixiu deformed body is located in the northwest of Huaying City,and the city will be in danger directly if the deformed body collapses.After analyzing the geological structure,deformation character,geomorphic evolution,human engineering activities in detail,the author has introduced numerical simulation into the article to study the case of formation mechanism of the deformed body.The study indicates that the deformed body has been gradually formed when the middle-obliquity reverse slope,which contains coal bed,was bended and ripped during the down-cutting of canyon.And human engineering activities,that is,excavating coal,influenced the development of the deformed body to great extent.更多还原
