在隧道施工中，垂直钻孔只显示钻孔位置可利用的土壤类型。钻孔之间的土壤剖面是不确定的，从业者出于施工目的而假设的。因此，隧道建造工程的生产力会受到不良泥土情况的影响。一种特殊用途的隧道模拟工具的成功实施证明，对土壤条件等不确定性进行建模可以提供更好的结果。本文提出了一种新的模拟算法来预测隧道沿线钻孔之间的土体过渡。过渡概率的使用使得能够预测过渡点。为了在专用隧道模拟模板内建模，考虑了土壤混合相的各种情况。将建模算法仿真应用于某施工项目，证明该建模算法能够对隧道推进速度进行合理、准确的预测。
In tunnel construction, the vertical boreholes only show the soil types that are available in the borehole locations. The soil profiles between the boreholes are uncertain and assumed by practitioners for construction purposes. The productivity of the tunnel construction work is therefore affected by adverse soil conditions. The successful implementation of a special purpose tunneling simulation tool identified that the modeling of uncertainties such as soil conditions could provide better results. This paper presents new modeling algorithms to predict the transition of soils between the boreholes along the tunnel path. The use of transitional probabilities enables to predict the transition points. The various scenarios of the mixed phases of soils are considered for modeling within the special purpose tunnel simulation template. Application of the simulation for modeling algorithms to a past construction project proved that this modeling algorithms provide a logical and an accurate prediction of the tunnel advance rate.
