Description

technical field [0001] The invention relates to a detection method in the technical field of coastal engineering, in particular to a numerical detection method for the anti-wave shock performance of a nuclear power plant breakwater. Background technique [0002] Breakwaters are widely used in important facilities such as coastal nuclear power plants and ports, and their structural design research is mainly done through wave model tests. During the structural design tests, it was found that the surface protection structure of breakwaters often overturned, lost stability, and was damaged. and so on. Therefore, there is an urgent need for a set of testing methods for the anti-wave impact performance of coastal breakwaters, which can guide the structural design of breakwaters and reduce test costs. [0003] After searching the existing technologies, it is found that there are many studies on simplified model tests of breakwaters and numerical algorithms based on them at home an...
