| Abstract: |
Through the years various immersed tunnels have been constructed using a relatively traditional technique. Although this is a traditional technique, the Mergor engineers focus on the optimisation of the existing techniques as well as on the demand for ingenious designs to meet the needs of specific local conditions. On recent projects a new type of modular bulkhead and closure joint were introduced. The immersion of an element under an existing monumental building is defined and the immersion of a tunnel element in a tight tidal window influenced by comparatively large tidal differences is explained. Besides these topics a short introduction of the recent projects is given. |
