Abstract

The invention discloses a wave impact resistance value detection method of nuclear power station breakwater. The method includes the following steps: providing three-dimensional geometrical reconstruction information of the breakwater according to geometrical section parameters and axial spatial geometrical parameters of the engineering breakwater; providing material property information of the breakwater according to used face-protecting structures and breakwater body engineering materials of the engineering breakwater; according to past hydrology record information of the breakwater, providing environmental information of wave impact resistance detection of the breakwater; establishing a three-dimensional local breakwater model by the aid of the material property information and geometrical design parameters of the breakwater; establishing a three-dimensional overall breakwater model by the aid of the material property parameters, the three-dimensional spatial geometrical parameters and calculation parameters prepared in the third step, and analyzing surface wave pressure and structural impact stress response distribution of the breakwater along the horizontal direction. By the method, the problem about local and overall performance detection of the coastal breakwaters is solved, design efficiency is improved effectively, and test randomness and capital investment are reduced.

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...
