摘要
监控量测作为隧道新奥法施工的三要素之一,通过量测数据,对数据进行分析处理能够有效反馈指导施工。基于多目标加权灰色局势决策法、模糊自适应变权重组合预测法建立最优非线性组合预测模型。在麻栗垭隧道中应用组合优化模型分析预测了拱顶沉降值,结果表明该模型对隧道施工过程围岩变形能够进行有效的预测和反馈。
Monitoring measurement is one of the three elements that are used in New Austrian Tunneling Method,by measuring the data,the analysis of the data can be effective feedback to guide the construction.Based on multi-objective weighted gray situation decision method and fuzzy adaptive variable weight combination forecasting method,the optimal nonlinear combination forecasting model was established.The combinatorial optimization model was used to predict the crown settlement in MaLiYa tunnel engineering.The results show that the model can effectively predict and feedback the deformation of surrounding rock during tunnel construction.
