Abstract Taking Cangling tunnel of Taizhou—Jinyun Highway as an example，the permeability coefficient of rock masses with different joint developments in tunnel are found out by hydrological geology integrated exploration method. Then water inflow in tunnel is forecasted using groundwater dynamics and groundwater modulus of runoff. Results show that the predicted location where inflow happens and the quantity of inflow approximate the practical ones，which indicates that the prediction of water inflow is of guidance to design and construction of drainage.
