陕西秦巴山区公路斜坡灾害发育规律的研究

秦巴山区是我国著名的山地灾害多发区.为了研究该区域公路斜坡的成灾机制和发育规律,通过对陕南G316国道早阳～蜀河段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.

Research on Development Law of Slope Hazard in Highways of Qinling-Daba Mountain

Qinling-Daba Mountain is the famous area frequently suffered from geological disasters in China.According to the geological survey on No.316 National Road from Zaoyang to Shuhe in the south of 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.On the basis of the statistical data,four impact factors of slope hazard are studied in further and their dominance is obtained,for studing disaster mechanism and development law of the slope.
