PREDICTION OF TUNNELLING EFFECT ON GROUNDWATER CONDITION BY THE WATER BALANCE BLOCK METHOD. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3
This article describes a method using the water block model and the tank model to predict the ground water levels, and liner and tunnel water discharge levels before, during and after tunnel construction. A case study is described where this method is used to predict tunnel discharge and the change in ground water level in a mountainous area around a newly constructed highway tunnel. The results show that the model is quick and easy to use. The geological condition of the area under analysis must be known, for the model to be used, as the coefficient of permeability and the effective porosity of the ground greatly affect the results. Provided that the model can be modified correctly during construction of the tunnel, the future hydraulic environment of the tunnel can be predicted accurately. (TRRL)
