| 摘 要： | 以白龙江苗家坝水电站库区巨型滑移-弯曲破坏模式的何家滑坡为例，在野外调研的基础上，利用理论公式、数值计算等手段，从地形、地应力、岩性组成和临空条件等方面分析了软硬相间层状斜坡产生滑移-弯曲模式变形破坏的成因机制。结果表明，研究区高、陡的地形条件、最大主应力平行斜坡走向的地应力条件，以及深部厚层软弱岩带的存在，是厚层状坚硬凝灰岩夹板岩斜坡孕育、发生滑移一弯曲模式变形破坏的主控因素。

| Abstract: | The authors have investigated the engineering geological conditions of the large Hejia landslide destructed by sliding-bending mode in the Miaojiaba hydropower plant reservoir area,then analyzed the formation mechanism of the sliding-bending distortion and destruction mode of the consequent bedded slope in the thick and rigid rock mass from the landform and geostatic stress along with lithological compages and so on,at one time making use of theoretical calculation and numerical simulation.The conclusion is... |
