| Abstract: |
Major bridge substructures like anchor blocks for suspension bridges and large offshore foundations for bridge towers and piers are generally exposed to very significant loads. Therefore, to achieve sustainable and resilient solutions for design of such structures, careful optimization of material consumption and adaption to the actual boundary conditions are needed. Also, accidental loads like earthquake and ship impact can be important design drivers. This calls for adaptation and innovation to find sustainable, resilient, and durable substructure solutions which can also be constructed fast and efficiently. This is illustrated by examples from COWi's history of substructure designs comprising a variety of solutions ranging from caissons to pile foundations and open dredged foundations. |
