本文基于隧道监控量测实测变形资料采用皮尔曲线进行隧道变形预测,利用所建的皮尔模型对荆竹山隧道围岩变形进行了预测分析;通过对比分析可得按照等时距皮尔预估模型拟合的曲线与实测变形曲线基本吻合;把新测得数据及时补充到预测模型中区,可使变形预测结果更加准确。这对确认支护参数和施工方法的准确性,为初期支护和二次衬砌设计参数的调整及指导二次衬砌施做的时间提供重要依据。
Based on the measured data of tunnel monitoring and measuring, the deformation of tunnel is predicted by Peel curve, and the deformation of surrounding rock of Jingzhushan tunnel is predicted by using the established Peel model. Through the comparative analysis, Of the curve and the measured deformation curve basically match; the newly measured data promptly added to the prediction model in the area, deformation prediction results can be more accurate. This confirms the accuracy of support parameters and construction methods, and provides important basis for adjusting the initial support and secondary lining design parameters and guiding the time of secondary lining.
