以大浏高速公路道吾山隧道为研究背景,结合现场实测资料,对道吾山隧道围岩稳定状态进行分析研究,利用围岩变形监控数据建立并优化灰色预测模型 GM(1,1),采用该模型对围岩位移变形进行预测,并将预测结果与现场监测结果进行对比分析,误差较小。应用灰色预测确定支护的最佳工作状态和支护结构工艺参数,并以此判别围岩的稳定性具有重要意义。
以大瀏高速公路道吾山隧道為研究揹景,結閤現場實測資料,對道吾山隧道圍巖穩定狀態進行分析研究,利用圍巖變形鑑控數據建立併優化灰色預測模型 GM(1,1),採用該模型對圍巖位移變形進行預測,併將預測結果與現場鑑測結果進行對比分析,誤差較小。應用灰色預測確定支護的最佳工作狀態和支護結構工藝參數,併以此判彆圍巖的穩定性具有重要意義。

Taking Daowushan tunnel of Daliu Freeway as a research background ,the steady state of the wall rock of the tunnel is analyzed here combining with the empirical testing data ,and the grey prediction model 〔GM(1 ,1)〕 is built and optimized with the monitored data about surrounding rock deformation ,then the surrounding rock displacement is predict-ed ,and the predicted result are analyzed and compared with field monitoring results ,it is found that both the numerical values are approximative .It has a great significance that this model is used to figure out the best working condition and technological parameters of shoring ,and then make a judgment to the stability of surrounding rock .
