Abstract
- The section K0 +785 -K0 +988 on the north shore of the Dalian Bay immersed tunnel, which is higher than the original seabed surface, is susceptible to ship collision risks and requires anti-collision measures. Taking into account factors such as construction difficulty, environmental protection, and cost, a permeable gravity pier foundation composed of circular caissons, column piles, and cast-in-place piers was proposed as the anti-collision structure, while meeting the requirements of the construction period. Combined with the structural form and main loads of the anti-collision pier, the overall stability of the anti-collision pier structure and the bearing capacity of the column piles were analyzed and calculated using finite element method and specification method. The results show that the permeable gravity pier anti-collision structure can meet the requirements of engineering use in all aspects, and can provide design reference for the construction of similar structures in the future.
