摘　　要：高性能防护网结合预应力锚杆具有较强的深层加固和局部块体的表层防护作用,在高位崩塌落石综合整治中具有明显优势。本文采用工程地质调绘、无人机测绘3D建模、病害调查和理论分析等方法对某高速公路隧道口9级路堑边坡的高位崩塌落石病害及其稳定性进行分析评价,经方案比选论证后采用高性能防护网结合预应力锚杆的措施对该病害边坡进行综合整治,消除了重大安全隐患,达到了预期效果,为各级公路边坡高位崩塌落石病害整治提供了可借鉴的工程经验。The combined application of high-performance protective nets and prestressed anchor rods has strong deep reinforcement and surface protection effects on local blocks,offering advantages in the comprehensive treatment of high-level collapse and rockfall.This study employs various methods,such as engineering geological mapping,3D modeling based on surveying and mapping with UAV(unmanned aerial vehicle),disease investigation,and theoretical analysis,to analyze and evaluate the high-level collapse and rockfall disease and the stability of the 9-stage cutting slope of a certain expressway tunnel exit.After comparing selection and feasibility demonstrating of various schemes,high-performance protective nets combined with prestressed anchor rods were selected to treat the affected slope comprehensively,which eliminated major potential safety hazards and achieved the expected results.This study provides a valuable engineering experience for the treatment of high-level collapse and rockfall diseases on highway slopes.
