摘要
介绍山西省太旧高速公路北茹隧道新奥法施工过程中监测围岩变形的项目、手段及数据处理方法。基于测试结果,分析了围岩变形的特性,建立了围岩收敛变形预测模型,预测了围岩失稳和基本稳定的时间。
The contents, technique, and data process method of deformation monitoring are described for the surrounding rocks of Beiru tunnel of Taijiu expressway designed and tunnelled with NATM. Based on the measured data, the deformation properities are analysed and the prediction model is formed for the convergence of sourrounding rocks. The unstable and restable times are predicted for the rocks. The effect of support is evaluated , as well.
