摘　　要：为进一步研究公路边坡危岩灾害的形成原因,找出影响其破坏程度的因素,并提出灾害防治对策建议,采用实地调查和理论分析的手段对永蓝高速进行了研究。查明了荷叶塘高架桥北侧危岩体的致灾环境,从地形地貌、气象水文、地层岩性、地质构造、水文地质条件等方面进行了分析;通过实地调查查明了灾害发生的原因,认为地层岩性和地质构造条件是影响危岩体发育的主要因素;最后针对该危岩体通过力学计算提出了"锚杆锚固+排水+挂网防护"的灾害防治对策。研究成果具有一定的适用性,可为公路工程防减灾提供一定的依据。This paper focuses on dangerous rock body of Yonglan expressway. The author studies causes of the dangerous rock disasters of highway slope and puts forward suggestions for disaster prevention by means of field investigation and theoretical analysis. It also identifies the disaster-causing environment of dangerous rock mass on the north side of Heyetang viaduct, and analyzes topography, meteorology and hydrology, lithology, geological structure, hydrogeological conditions, etc; it also finds out the reasons for disasters by field survey： the study shows that the conditions of formation lithology and geological structures are main factors affecting the de- velopment of dangerous rock mass; disaster prevention measures against the dangerous rock mass of ＂bolt an- choring ＋ drainage ＋ linked network protection＂ are put forward through mechanics calculations. The re- search provides a basis for disaster prevention of highway engineering
