Immersed tunnel technology: a brief history of its development
Journal Title: Civil and Environmental Engineering Reports - Year 2010, Vol 1, Issue 4
Abstract
The first tunnel made of segments, which were sunken and then merged under water, was built in 1896. It was a passage for conducting sewerage under Boston Harbor. The first tunnel for passenger traffic was constructed ten years later, also in the United States. Since then more than one hundred immersed tunnels of different size and length have been built worldwide. But the rise of "build-and-sink" technology is much older than that. Before the Boston Harbor tunnel was built the method has been theoretically elaborated in numerous patents and subsequent proposals. After that practically verified and perfected to the present form. Today’s “build-and-sink” technology allows constructing floating immersed tunnels, buried in a sub aqueous trench or simply laid on the bottom. The case of immersed technology is shown as an example of a technique, which was invented ahead of its time.<br/><br/>
