Abstract: A case history of surcharge-induced large deformations and noticeable leakages occurring on existing underlying twin tunnels in soft ground is presented in this paper. The field conditions are well-documented in terms of ...

Abstract: A field test for investigating the soil arching effect behind the diaphragm wall was carried out in an average 17-meter-deep, braced excavation in the normally-consolidated clayey ground. Horizontal and vertical ground ...

Abstract: Excavation-induced soil arching is a key factor influencing the responses of the ground and underlying structures. This soil arching below an excavation base is defined as downward soil arching in comparison with that above ...

Abstract: Excavations near an existing tunnel are frequently encountered in underground construction. The excavation–soil–tunnel interaction mechanism is not yet fully understood, notably the long-term behavior. This study carried ...
