摘　　要：黑山南北高速公路Smokovac-Matesevo段复理石地层广泛分布,路堑边坡防护量较大。由于当地环保绿化要求,混凝土骨架防护不能大规模应用于路堑边坡防护,依据当地及周边国家规范标准体系,路堑边坡防护最终主要采用了锚杆加挂网的防护形式。首先结合实际地质断面利用PLAXIS软件分析锚杆挂网防护对复理石边坡稳定性的影响,其次对锚杆挂网在复理石边坡防护施工过程中遇到的问题进行分析,总结锚杆挂网防护实际应用中应注意的问题,以期为后续项目路基边坡防护设计施工提供更合理有效的指导。In Smokovac-Matesevo section of Montenegro South-North highway,flysch rock layer is widely spread,quantity of cut slope protection is great.Due to requirements of environment protection and highway planting,concrete skeleton protection cannot be widely used to protect cut slope.Based on local standards and standards of surrounding countries,anchors and mesh is finally adopted to protect the cut slope.PLAXIS software is first used to evaluate the influence of anchors and mesh on stability of flysch cut slope with actual geological cross section,then problems encountered during construction of anchors and mesh protection is analyzed.Issues in application of anchors and mesh protection is summarized at last in order to provide more reasonable and effective guidance for design and construction of slope protection of future project.
