地表注浆加固在滑坡治理中的应用分析

Application Analysis of Surface Grouting Reinforcement in Landslide

以大庆至广州高速公路南康至龙南段扩容工程马槽仔隧道进口滑坡为例,通过对不同地表注浆方案经济技术指标的对比,并考虑实际施工的可操作性,综合确定地表注浆加固方案。同时对于地表注浆加固的效果采用数值模拟计算与实测数据对比的方法,验证了地表注浆在滑坡处理中的有效性和可行性。具有很高的参考和实用价值,可以为今后类似项目提供指导和借鉴。

This paper takes the landslide at the entrance of the Macaozai Tunnel in the expansion project of Nankang-Longnan section of Daqing to Guangzhou Expressway as an example.By comparing the economic and technical indicators of different surface grouting methods,and considering the operability of the actual construction,the surface grouting method is determined.At the same time,the effect of surface grouting is compared by the numerical simulation calculation with the measured data,which verifies the effectiveness and feasibility of surface grouting in landslide treatment.It has high reference and practical value and can provide guidance and reference for similar projects in the future.
