Collapse Mechanism of Tunnel below Underground Structure
Abstract: The collapse mechanism of a tunnel in free field sandy soils with a high water table is generally known as cone- or chimney-shaped. However, when a tunnel is constructed below an underground structure with a much larger width than the tunnel diameter, the stiffness of the structure significantly affects the settlement profile and even the collapse mechanism. The recently reported tunnel...

Effect of Ground-born Vibration Induced by Intersecting Tunnels
Abstract: Vibration and noise are not only environmental but also dynamic problems, and they have become more important engineering and environmental issues as much as a concern about the quality of urban life. The increase of traffic demand in urban area and high speed railway connection between cities has caused a new issue in which the train tunnel adjoins or intersects within the city. For the case...

Smart Control of Hydraulic Actions in Tunnels and Underwater Structures
Abstract: Selecting the tunnel type is very important in subsea and subriver tunnels if the difference between ordinary water level and flood water level is very high or if the difference between wave and tide levels is considerable. This is because, in the case of a drained tunnel, excessive influent disposal can be a large burden during operation, and for watertight tunnels, lining damage may occur...

Weep Hole Design in Water Conveyance Tunnel
Abstract: Water supply mains and inland ware net-working systems require large scale of water conveyance tunnels. Recently, to control flood and measure drought, 11 km of water conveyance tunnel connecting two earth and rockfill dams was constructed in South Korea. The tunnels are generally located in the mountain areas and constructed as drains. Circular concrete liners without drainage system were...
