Comparative Analysis of Tunnel Inflow Forecast

Guang LUO, Wei-zhen BAI, Yun ZHANG


This paper summarizes the calculation method of tunnel water inflow and its applicable conditions, and enumerates the theoretical calculation formula of some tunnel water inflow. In order to reduce the error between the predicted value and the measured value of The La Yi Tunnel water inflow, based on the existing tunnel water inflow calculation formula, the tunnel engineering geological data are used for calculation, and the calculated values of the formulas are compared with the measured values to select the suitable tunnel. The theoretical calculation formula for the predicted value of water inflow. The research results provide a theoretical basis for the prediction of the tunnel water inflow and expansion, and provide reference to the prediction of the tunnel water inflow in this area.
