公路边坡的稳定性由内在因素和外在因素所决定。内在因素是边坡本身所固有的,外界因素主要包括降雨、地震、开挖等。近年来,降雨导致公路边坡失稳进而影响交通的情况越来越多。祥临公路地处气候湿润多雨,地质灾害频发,运用降雨入渗相关理论,对其进行边坡稳定性分析,得知该路段安全系数小于1.05,边坡处于不安全状态,需要进行防护加固。 The stability of highway slopes is determined by intrinsic and extrinsic factors. Internal factors are inherent in the slope itself, external factors include rainfall, earthquakes, excavation and so on. In recent years, rainfall has caused more and more road slopes destabilizing and thus affecting traffic. Xianglin highway is located in humid and rainy weather, frequent geological disasters, the use of rainfall infiltration theory, its stability analysis of the slope, that the road safety factor of less than 1.05, the slope in an unsafe state, the need for protection and reinforcement .
