| 摘 要： | 秦巴山区是我国著名的山地灾害多发区。通过对陕南G316国道斜坡灾害的实地调查,总结了斜坡灾害点的基本情况,指出研究区的地形地貌、地质构造、气象水文等地质环境条件有利于斜坡灾害的孕育。在此基础上,进一步研究了坡度、坡高、坡向及坡形等基础因子对斜坡稳定性的影响,并提出了各影响因子的优势度。同时,归纳了该路段斜坡灾害的变形破坏特征,总结出顺层滑动、弯曲-倾倒、楔形体滑动、溃曲破坏以及滑移-拉裂5种典型的失稳模式,并对每种模式进行了具体的实例分析,从而为边坡成灾预警和选择经济有效的治理对策奠定基础。

| Abstract: | Qinling-Daba Mountain is the famous area frequently suffered from geological disasters in China.According to the geological survey on No.316 national road in the southern shaanxi province,basic situation of slope hazard is concluded to ascertain geological environment characteristics.It is shown that geological environment characteristics,including topography,geological structure,meteorology and hydrology,are benefical to the preparation of slope hazard.Based on the statistical data,four impact factors of s... |
