摘　　要：基于隧道掘进机(tunnel boring machine,TBM)施工过程和施工工艺,融合三维地质建模技术和工程仿真技术,建立长隧道三维地质模型和施工循环网络仿真模型,实现长隧道TBM施工过程的可视化与施工进度的仿真预测。以西藏DXL隧道工程为研究对象,耦合DXL隧道三维地质模型,通过仿真计算对DXL隧道TBM施工段进度计划进行优化分析,统计拟合完工概率随施工工期变化的函数曲线,计算出预期完工概率,实现了施工过程的可视化,并提出保障施工进度的措施和建议。Based on the analysis of the tunnel TBM construction process and technology,using the three-dimensional geological modeling technology and engineering simulation technology,a construction cycle network simulation model was established,which could achieve the prediction and visual analysis of TBM tunnel construction process.Taking the DXL tunnel project in Tibet as the research object,coupled with the three-dimensional geological model of the DXL tunnel,an optimized analysis of the TBM construction schedule of the DXL tunnel was performed through simulation calculations.The relationship between the completion probability and the construction time was fitted,and the expected completion probability was determined.The construction process was visualized and suggestions to guarantee the construction progress were proposed.
