Method for evaluating unworkable time of port

The invention discloses a method for evaluating the unworkable time of a port, and the method comprises the steps: 1, obtaining a wave time sequence of a near-shore position in a preset time period, carrying out the wave height-period-wave direction joint distribution statistical analysis, and obtaining a wave height-period-wave direction joint distribution result; 2, for different berths, respectively measuring eight dynamic response parameters under each group of typical wave condition combinations; 3, obtaining a quantitative relationship between the maximum value of each dynamic response parameter of each berth under the action of various wave conditions and incident waves; and step 4, for different berths, the cumulative override frequency of the eight dynamic response parameters of each berth is counted, non-operation time results Di corresponding to the eight dynamic response parameters are obtained, and the non-operation time results at the berths are the maximum values of the non-operation time resul
