摘要
结合烟台万华洞库工程资料和现场监控量测数据,应用FLAC3D数值分析软件,对巷道的开挖支护进行模拟分析。通过对比分析模拟计算结果与监测数据,从拱顶下沉值、围岩收敛、围岩内部位移三个方面来分析围岩的变形规律,同时验证所建模型的可靠性。
Combining with the project datas and local monitoring measures of WAN HUA tunnel in YAN TAI city, analyse the roadway excavation by FLAC3D software. Through comparing compute result with monitoring measures, analyse the deformation from the vault subsidence value, the convergence and inter nal displacement of surrounding rock, and then test the model＇s veracity.
