Description

technical field [0001] The invention relates to the field of engineering measurement, in particular to a wave action kinetic energy measurement device, method and application thereof. Background technique [0002] In the eastern coastal areas of China, there are many people and little land, and the land space is limited. In order to meet the traffic demand, it is often necessary to build a large number of cross-river and sea-crossing tunnels. Immersed tube tunnels are one of the more common types of tunnels. Dalian University of Technology's research paper "Simulation Research on the Submersion Process of Ultra-Long Immersed Tube Sections" mentioned that underwater immersed tube tunnels will be affected by factors such as waves and currents during construction. Laying is an important link in the construction of immersed tube tunnels, and it is also the most dangerous link. The completed Hong Kong-Zhuhai-Macao Sea-crossing Bridge also encountered the safety test of immersed ...
