Application of High-Performance Protective Nets Combined with Prestressed Anchor Rods in Comprehensive Treatment of High-Level Collapse and Rockfall on Highway Slopes
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.
