Considering tunnel engineering conditions, we proposed a blockage model of tunnel drainage pipe in the non-karst area based on the calculation of calcium carbonate fouling rate. The model was used to calculate blockage time of the drainage pipe for existing and under construction tunnels. For existing tunnel, the calculation result of the model is close to the measured results, thus verifing the validity of the model. For under construction tunnel, in order to prevent the drainage pipe from being blocked within 20 years, Ca2+ leaching rate of primary support concrete subjected to 6 mol/L NH4Cl solution eroding for 14 d should not exceed 0.032%.
