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G 316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。
Qinba Mountain is a famous mountainous area in our country. In order to study the disaster mechanism and development law of the highway slopes in this area, the basic situation of the slope disaster points was summarized through the field survey of the slope disasters in Ziyang ~ Shuhe section of G 316 national highway in southern Shaanxi Province. The topography, geology Geological and environmental conditions such as tectonics, meteorology and hydrology are conducive to the breeding of slope disasters. On this basis, the influence of basic factors such as slope, slope height, aspect and slope shape on slope stability is further studied, and the dominance degree of each influencing factor is also proposed.
