【摘要】 高陡易风化岩边坡一经开挖,坡面易出现风化剥落与溜塌等病害事故。据此,本文依托340省道工程,阐述了高陡易风化岩边坡护坡设计中,强化压脚支挡、分级踏面护角、锚杆框架梁等边坡支撑稳定与抗风化措施的必要性;同时论证了短钉挂金属网+厚基质客土喷附技术组合护坡方案;经验证,综合坡面加筋、柔性支撑、坡面封层保湿与坡面绿化等多功能协配统一的治理方案具有良好的效果。更多还原

【Abstract】 Geological hazards such as weathering, spalling and slumping are easily caused by the excavation of high-steep and easily weathered rock slope. Based on this fact and Nanjing 340 Provincial Highway reconstruction and extension project, the necessity of slope support such as toe retaining, stepped tread protection and anchor frame beam in high-steep and easily weathered rock slope protection design to increase stability and weathering resistance is elaborated. At the same time, the combination of short nails hanging metal mesh and thick-layer matrix spray-adsorption method for slope protection is demonstrated. The integrated treatment of slope reinforcement, flexible support, slope moisturization and greening has achieved good results.更多还原
