Calcium leaching of a concrete tunnel lining under aggressive groundwater conditions
Abstract: Urban railway tunnels are an important infrastructure for public transportation. A lin-ing of concrete is often cast to support the ground and protect the internal services in the tunnel. The durability of the concrete lining can be affected by the properties of the local groundwater. The water can flow through cracks or joints in the concrete and then start to attack the concrete from the...

Method for water inflow rate estimation from sample measurements of surface flows on tunnel walls
Abstract: Water inflow rate is an important factor in the assessment of tunnel conditions. Excessive water inflow could cause corrosion of metallic services, short circuiting of electrical devices and generally create a hazardous environment within the tunnel. A method for estimating the water inflow rate along a tunnel wall is developed by considering various crack and joint orientations and locations...
