九日山摩崖石刻危岩体成因分析及加固工作方法论述

Cause Analysis and Reinforcement Method of Dangerous Rock Body of Inscriptions on Precipices in Jiuri Mountain

针对九日山危岩体存在崩塌、滑移、倾倒的问题,论文以九日山危岩体为例,叙述了常见的加固措施,分析了危岩体机理现状,同时针对其成因进行了探究,采用微型锚杆结合裂隙灌浆和砌筑的方法解决了石刻周边危岩体存在的安全隐患,对石刻本体的保护起到了极其重要的作用。结果表明:以锚杆为主的加固以及以砌筑为主的加固方法的运用,均有利于提高危岩的稳定性。

Aiming at the problems of collapse,slip and toppling of the dangerous rock mass in Jiuri Mountain,taking Jiuri Mountain dangerous rock mass as an example,this paper describes the common reinforcement measures,analyzes the mechanism of dangerous rock mass,and explores its causes.Micro-anchor combined with crack grouting and masonry are adopted to solve the safety risks of dangerous rock mass around the stone carvings,which plays an extremely important role in protecting the stone carvings.The results show that the use of bolting as the main reinforcement method and masonry as the main reinforcement method is conducive to improving the stability of dangerous rock.
