Design method of ice-resistant system of offshore photovoltaic power station and ice-resistant system

Abstract

The application belongs to the technical field of offshore photovoltaic power stations, and provides a design method of an ice-resistant system of an offshore photovoltaic power station and the ice-resistant system. The design method comprises the following steps: based on the scale parameters of a photovoltaic power station site, sea ice conditions and geological conditions, the preliminary parameters of a vertical pile array and the vertical piles in the photovoltaic power station site, the sea ice parameters and the rock-soil mechanics parameters are determined respectively; an inclined pile is arranged outside the periphery of the vertical pile array in the photovoltaic power station site; according to the sea ice parameters, the rock-soil mechanics parameters and the shielding coefficient generated by the vertical pile array, the ice force borne by the vertical piles in different regions of the vertical pile array is obtained, the preliminary parameters of the vertical piles are reviewed based on modeling calculation, and the parameters of the vertical piles are updated; a certain number of seawater connecting devices are arranged in the photovoltaic power station site to ensure that the pressure above and below the fixed sea ice is the same; based on the relationship between the pile length and the pile diameter and the vertical pile uplift capacity, the pile length and the pile diameter in the vertical pile parameters are finally determined.
