A Case study on the Improvement of Tunnel Drainage systems

Since the urban subway is normally constructed under the groundwater level, the drainage system will be one of the most important factors during maintenance period. Therefore, to investigate suitability of the design approach and the construction specification, the inflow and the contents of the groundwater in the Route 5 of Seoul subway system are analysed. From these, the possibility of the design improvement and the economy of the maintenance cost are proposed.
