烟台五卒山大跨隧道围岩变形预测分析

Rock deformation prediction analysis of grand cross tunnel of Wuzu mountain in Yantai

烟台五卒山隧道作为双向八车道大跨隧道,在隧道施工过程中开展了监控量测工作,并对监控数据采用最小二乘法进行位移最终预测,预测结果表明所选模型可较好的反映隧道围岩的变形趋势,且最终预测量满足规范要求,证明隧道施工中围岩稳定。

Yantai Wuzu mountain tunnel is a two-way eight-lane tunnel span, in the tunnel construction process monitoring and measurement work carried out, and the final displacement monitoring data using the least squares method to predict. The results showed that the selected mod- el can predict better reflect the trend of surrounding rock deformation and ultimately predict the amount required to meet the specifications, indi- cating stability of surrounding rock tunnel construction.
