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...
Abstract: With the rapid development of urbanization in China, a large amount of metro constructions have been carried out in recent years. Dozens of shield TBMs driving simultaneously in the downtown area has raised up challenges for more efficient construction management. The lack of timely information communication and cooperation between all the participants involved in the project, especially the...
Abstract: The micro-disturbed construction in mix ground is a major challenge in the shield tunnelling construction. The Nanning metro line 1 crossing a mass of buildings is confronted with the challenge of round gravel and mudstone. The settlement control scheme consisting of the selection of TBM, tunnelling parameters optimization was put forward before crossing the buildings. Then the mix proportion...
