Region prediction method for sea wave field and wind speed field of cross-sea bridge construction

Abstract

The invention discloses a region prediction method for the sea wave field and wind speed field of cross-sea bridge construction, and the method comprises the steps: obtaining sample sea wave data forecast by a marine meteorology organization before the construction of a construction sea, and building a sample sea database; enabling the construction seat to be divided into a plurality of prediction monitoring regions, obtaining the actual measurement wave data of each prediction monitoring region, and building all prediction monitoring region databases; taking the sample sea database as an input learning sample, taking all the prediction monitoring region databases as output samples, and respectively building the corresponding relation between the actual data of each prediction monitoring region database in each day and the forecast data in the sample sea database at this day; extracting the wave height and wind speed forecast data of the sample sea in a future time period from the marine meteorology organization, taking the wave height and wind speed forecast data as the input data, and calculating the corresponding wave height and wind speed forecast data of each prediction monitoring region in the future time period. The method provides environment guide for the bridge construction.

Description

technical field [0001] The invention relates to the technical field of marine weather forecasting, in particular to an area forecasting method for wave fields and wind speed fields in sea areas where cross-sea bridges are constructed. Background technique [0002] The construction of cross-sea bridges generally needs to face various unfavorable natural conditions such as changeable meteorological environment, complex submarine geology, and harsh hydrological conditions. The construction difficulty is much greater than that of inland river bridges with the same span and scale. Since the construction of the cross-sea bridge has a certain dependence on the natural environment of the site, for example, strong winds will affect the hoisting of structures with large wind-affected areas such as formwork and casings; when the sea wave height exceeds the safety limit, the ship cannot carry out construction materials and machinery Transportation and transportation, making the construc...

AI Technical Summary

Problems solved by technology

Therefore, there is a certain gap between the forecast data of the marine meteorological forecasting agency and the actual wind and wave data in the construction area of ​​the cross-sea bridge, and the accuracy is not enough to guide the formulation of the construction plan
