A new method for structural health evaluation of shield tunnel
Abstract: This study presents a new method for evaluating structural health with shield tunnels. As a fuzzy system, evaluation of tunnel health has the characteristics of randomness and fuzziness. Traditional tunnel health evaluation methodologies do not account for the fuzziness and randomness of the system. Therefore, using cloud theory, this study puts forward a new the method for evaluating tunnel...

Numerical Simulation Analysis on Piston Effect Induced by a Running Train in Subway Station
Abstract: Effective utilization of the piston wind induced by metro trains is a meaningful research point. A numerical methodology to simulate a train entering and leaving the subway station by using dynamic grid technique was proposed. The longitudinal distribution of piston wind in the tunnel space inside the station, the variation for the piston wind volume with train’s running states and the...

Variations of Atterberg Limits of Clays and Their Chemical Mechanism Due to Soil Conditioning
Abstract: To determine of ideal type and content of soil conditioners for earth pressure balance (EPB) shield tunneling in clayey ground, this study investigates effects of soil conditioners on Atterberg limits of clays and conditioning mechanism based on their chemical effects. The applicability of soil conditioners (including foam and dispersant) was determined based on the changes of Atterberg limits...
