Název v původním jazyce

An investigation of perpendicularly crossing twin-tunnel interaction

Popis výsledku v původním jazyce

Any tunnel driving inevitably induces stress changes and deformation in the ground as well as adjacent substructures such as existing tunnels. Due to the shortage of lands and environmental needs in major cities worldwide, tunnels are constructed closerand closer. The interaction between tunnels is complex and still not fully understood. In this study, a three-dimensional centrifuge test was carried out to investigate the interaction between an existing tunnel and a new tunnel excavated perpendicularlyacross underneath in sand. A novel technique that simulates the effects of both volume and weight losses due to tunnel excavation has been recently developed to mimic three-dimensional effects of tunnel advancement in-flight. The test was also back-analyzed three-dimensionally using a non-linear constitutive model considering small strain stiffness. In-terpretations of measured and computed results are reported and discussed.
