Abstract: For the tunnel construction, mooring is one of the most important procedures before the tunnel immersion. For the cross-sea project, the effects of swell, current and wind seas on the mooring system must be investigated in detail. This is achieved by using an approach of combined scale model tests and numerical simulations. Model tests for tunnel mooring were carried out in a towing basin. The...
Abstract: The Shenzhen Yanjiang Highway Qianhai-Nanping Transit Project is an EPC contract that covers feasibility study, conceptual design, pre-design, construction design, procurements of facilities and equipment, and constructions. The project is located in the centre area of the Qianhai and Bao'an of Shenzhen city, on the east coastline of the Pearl River. The immersed tunnel that is part of the...
Abstract: For traditional immersed tunnel construction method, segments are clamped together temporarily by longitudinal prestressing cables which are later cut off at each of the joints after the tunnel element has been placed. This form of tunnel element can be called as the flexible scheme and has the advantages of deforming more freely with the ground and reducing the internal force produced in the...
