A Method for Predicting the Maximum Wind and Waves Used in the Construction of Cross-sea Bridges

Abstract

The invention discloses a maximum wind wave forecasting method for construction of a sea-crossing bridge, relating to the technical field of construction of sea-crossing bridges. The maximum wind wave forecasting method comprises the following steps: setting at least one monitoring point in a bridge construction sea area, and installing a monitoring instrument at the monitoring point; acquiring wind wave monitoring data in real time through the monitoring instrument, and uploading the wind wave monitoring data to a database of a remote server; obtaining open sea wind wave data of an open sea area, which the bridge construction sea area belongs to, and uploading the open sea wind wave data to the database of the remote server; establishing a proportional relationship of the two according to the daily maximum value of the monitoring data and the daily maximum value of the open sea wind wave data in the same period and stored in the database, and performing probability statistical analysis to obtain a statistical parameter; and obtaining the daily maximum value of open sea wind wave forecasting data of the open sea area, which the bridge construction sea area belongs to, in the future time slot, and calculating by utilizing the daily maximum value of the open sea wind wave forecasting data and the statistical parameter so as to obtain the daily maximum wind wave forecasting data of the bridge construction area in the future time slot.

Description

technical field [0001] The invention relates to the technical field of sea-crossing bridge construction, in particular to a maximum wind wave forecasting method for sea-crossing bridge construction. Background technique [0002] With the increasing demand of China's social economy for transportation, the construction of cross-sea bridges has developed unprecedentedly in recent years, and world-class cross-sea bridges represented by Hangzhou Bay Bridge and Hong Kong-Zhuhai-Macao Bridge have been built Bridges under construction are typically represented by the Pingtan Sea-Crossing Bridge. [0003] During the construction of cross-sea bridges, excessive wind and waves in the construction sea area will affect the safety construction of the bridge structure and the bridge. Generally, the construction wind and wave threshold should be set during the specific construction. In the case of extreme wind and waves, the bridge construction site needs to be considered. Protection and s...

Problems solved by technology

[0004] The bridge construction sea area generally belongs to a relatively large open sea area. The traditional wind and wave early warning measures are formulated based on the weather forecast of a certain open sea area announced by the Marine Meteorological Forecasting Station. Since the bridge construction sea area is generally close to the mainland, it belongs to the marginal area of ​​the open sea area. Therefore, the wind and waves in the bridge construction sea area are often smaller than the weather forecast announced by the marine meteorological forecast station, which makes the reference value of the weather forecast drop a lot, which is not conducive to the optimal allocation of bridge construction resources, construction arrangements and process control.
