摘要
为进一步研究高速公路边坡危岩灾害成因,找出影响其破坏程度的因素,并提出灾害防治对策,采用现场调查和理论分析的手段,查明了某高架桥北侧危岩体的致灾环境,从地形地貌、水文地质条件、地层岩性等方面进行分析;通过现场调研查明致灾原因,认为地质构造与地层岩性是影响危岩体发育的主要因素;最后通过力学计算提出"锚固+排水+挂网防护"的灾害防治措施。研究成果具有一定适用性,可为公路工程防减灾提供一定的依据。
For the further research on the causes of highway slope dangerous rock disaster and finding out the factors affecting the extent of damage, using field investigation and theoretical analysis method, this paper analyzed the disaster-causing environment of a highway viaduct dangerous rock mass from the topographical geomorphology, hydrological conditions and formation lithology etc. Through the mechanical calculation, it also put forward ＂anchor ＋ drainage ＋ hang net protection＂disaster prevention and control measures. The research results had certain applicability, which could provide certain basis for highway engineering disaster prevention and mitigation.
