This application discloses a method and system for assessing extreme environmental conditions in coastal engineering, relating to the fields of marine and coastal engineering technology. The method includes: establishing wave propagation deformation conversion relationships; performing quality control on multi-source wave-tide data; performing tidal level decomposition on the total water level time series; identifying multiple independent extreme wave-tide coupling events, extracting characteristic parameters to form a multi-dimensional extreme sample set, and establishing a joint distribution model; determining the target probability level and constructing an environmental profile with equal exceedance probabilities; selecting representative combined operating conditions, and using the wave propagation deformation conversion relationships to convert the representative combined operating conditions to nearshore control points to obtain design wave elements. This application, driven by multi-source wave-tide data, establishes a joint distribution model of wave height, period, and tidal level and constructs an environmental profile with equal exceedance probabilities, achieving quantitative determination of extreme design wave conditions with clear joint probability meanings, thus improving the scientific and economical nature of coastal engineering design.

The application discloses an anchoring device for floating photovoltaics, which comprises a hollow pile with a plurality of through holes in the top, a counterweight module and a plurality of anchor ropes; the bottom of the hollow pile extends into the seabed and is fixedly connected with the seabed, and the top is located below the sea surface; the counterweight module is arranged around the outer wall of the hollow pile and is connected with the upper surface of the seabed; and the plurality of anchor ropes are arranged on the pile body of the hollow pile and are flexibly connected with the pile body. The anchoring device for floating photovoltaics can adapt to large deformation of wind, wave and tide, has remarkable anti-pulling effect, can prevent scouring, has good stability and effectively guarantees the safety of the floating photovoltaic system. Meanwhile, since the main components are all prefabricated parts, the installation difficulty is reduced, the problem of large offshore construction difficulty and low safety is solved, and since the hollow pile is clearly positioned, the construction progress is accelerated, and the anchoring device is suitable for large-scale offshore photovoltaic development.
