Old line differential wind-proof evaluation method, apparatus and device, and medium

Abstract

The invention discloses an old line differential wind-proof evaluation method, which takes a wind speed recurrence period of 50 years as a reference, obtains load factors of wind speed recurrence periods of different years, and according to the load factors of wind speed recurrence periods of different years, determines the reliability grade of recurrence periods corresponding to the load factorsof wind speed recurrence periods of different years; the wind load regulation coefficients and wind pressure non-uniformity coefficients corresponding to different voltage levels are extracted from different design codes; the wind pressure non-uniformity coefficient and wind load adjustment coefficient are obtained when calculating wind load under different voltage grades; an equivalent factor ofthe tower line system is calculated according to the wind pressure non-uniformity coefficient and the wind load adjustment coefficient; according to the equivalent factor of the tower-line system, thereliability level of the corresponding equivalent factor is determined; the reliability level of the tower line is determined by comparing the reliability level of the recurrence period with the reliability level of the equivalent factor. The wind-resistant reliability of transmission towers can be evaluated effectively by adopting different evaluation methods for transmission towers with different design specifications.

Description

technical field [0001] The invention relates to the technical field of performance evaluation of engineering structures, in particular to a method, device, equipment and medium for evaluating wind resistance of old lines in differentiation. Background technique [0002] Due to the different standards followed and the different construction environments in history, the wind resistance capacity of existing lines is uneven, and a large number of existing lines have insufficient wind resistance capacity. According to the evaluation of the existing design system, the proportion of existing lines that do not meet the wind resistance design requirements is relatively high. Since the wind-resistant reinforcement of lines not only involves massive construction funds, but also involves complex economic, social and technical factors such as land acquisition, planning and construction, and power outages, it is necessary to comprehensively consider the wind-resistant capacity of the line...
