清除高陡边坡危岩体施工中锚拉预应力钢丝绳应力特征研究

依托珠海市某中学后山边坡崩塌防治工程，对岩体加固的预应力钢丝绳的应力应变进行了监测分析。通过对4个典型的危岩体钢丝绳应力的监控，得出钢丝绳的受力随危岩体逐层破解过程中的变化规律，分析了锚拉钢丝绳在危岩体逐层破解过程中的工作状态，确保施工过程中危岩体处于稳定状态，清除了施工过程中的安全隐患。

Stress Characteristics Study on Anchor and Prestressed Wire Rope in the Coustruction of Removing Dangerous Rock Mass of High and Steep Slope

Relying on the prevention project for slope collapse of a secondary school in Zhuhai, the stress strain of prestressed steel wire rope strengthened by rock mass is monitored and analyzed. By selecting four typical dangerous rock masses to monitoring of wire rope stress, the variation rule of wire rope stress in the cracking process of dangerous rock mass layer by layer is obtained and the working state of anchor wire rope in the cracking process of dangerous rock mass layer by layer is analyzed. It is of great significance to ensure that the dangerous rock mass is in a stable state during the construction process and eliminate the hidden danger in the construction process.
