New Stability Analysis Method for High Cutting Loess Slope——Quick Search Method for Special Slide Surface

Journal: JOURNAL OF EARCH SCIENCES AND ENVIRONMENT

Keyword:  黄土高边坡抛物线形滑裂面稳定性分析方法;
Abstract: 黄土路堑高边坡自身的特点,决定了其失稳破坏时滑裂面的特殊特征.综合考察大量失稳黄土高边坡实例,发现其滑裂面剖面形态多呈上陡下缓的"L"形.利用传统稳定系数的概念进行分析,与实际情况出入较大.利用数学方法,将黄土路堑高边坡的滑裂面概化为"抛物线"形,推导出其稳定性分析表达式,建立特殊滑裂面快速搜索的方法.实际检验表明,该方法弥补了其他分析方法的不足,更符合实际.
