巴万高速典型边坡危岩分析与处治方法研究

Analysis and Treatment of Dangerous Rock on Typical Slope of Bawan Expressway

随着国民经济的快速发展,跨山区的高速交通愈发受到重视,而山区地质灾害频发,边坡危岩属于山区的典型地质灾害,因此,山区高速公路尤其需要做好边坡危岩的处治工作。基于此,本文对边坡危岩的失稳方式进行了讨论,并根据巴万高速某边坡危岩工程实例,提出采用柔性主动防护网技术与静态膨胀破碎法相结合的施工方案进行边坡危岩处治,并对该方案的工艺流程进行了介绍,为同种类型的边坡危岩处治提供了思路。

With the rapid development of the national economy,cross-mountain high-speed traffic has been paid more and more attention,but geological disasters occur frequently in mountainous areas,and the perilous rock is a typical geological disaster in mountainous areas.Therefore,it is especially necessary to do a good job in the treatment of perilous rock on mountain expressways.Based on this,this paper discusses the instability mode of the perilous rock on slope,and puts forward a construction scheme combining flexible active protective net technology and static expansion crushing method to treat the perilous rock on slope according to an example of the perilous rock on slope in Bawan expressway,and introduces the process flow of the scheme,which provides ideas for treating the same perilous rocks on slope.
