为进一步研究秦巴山区公路崩塌灾害的影响因素和形成原因，减轻灾害对山区公路交通的影响并提出相应防治对策，采用实地调查和理论分析的方法，对G108周至、佛坪和宁强段崩塌情况进行了研究。查明了区内主要环境条件；调查了20处崩塌灾害点，根据受力状态和灾害形态将崩塌分为滑塌、劈裂和碎落等3类，并对其中规模较大、成因复杂的3处灾害点进行了分析；从内在因素和外在因素两方面探讨了崩塌灾害的影响因素，从边坡坡度、坡面形态、岩体性质、降雨条件和人类工程活动等方面研究了崩塌灾害的形成原因；最后从加强监测、完善排水、边坡防护和工程治理等4个方面提出了灾害防治对策。研究结果可为陕南秦巴山区公路崩塌灾害防治提供一定的参考。

In order to study the impacting factors and causes of collapse disasters of highway in Qin-ba mountainous area , to mitigate disaster impact on highway traffic and to propose corresponding prevention and countermeasures , a field survey and a theoretical analysis method were used to re-search the collapses in G 108 Zhouzhi , Foping and Ningqiang sections .The major environmental conditions of the area and 20 collapse points were identified , which were divided into slumping , splitting and recollected fragments according to the loading states .Three large scale disasters with complex genesis were analyzed;the impacting factors of the collapses were explored from the internal and extrinsic aspects;the causes of the collapses were investigated from the aspect of the angle of slope, slope morphology, rock mass property, rainfall conditions, human activities and other as-pects.Disaster prevention and countermeasures , such as strengthening the monitoring , consumma-ting drainage, slope protection, and engineering governance, etc., were put forward.This study could provide certain reference for disaster prevention and control of highway collapses in southern Shaanxi Qinba mountainous area .
