柔性光伏支架因跨度大、桩数少、离地高度调节空间大等特点，逐渐在渔光互补光伏项目中广泛应用。随着项目规模的提升，单一柔性阵列长宽均可达数百米。本文通过对不同排跨柔性支架进行建模，分析其受力变化情况，结果表明，当连续跨计算跨数达到7跨后，各索索力误差与全阵列相比在5%以内，可用于近似替代计算，但反拱索及横向斜拉索索力随排数变化较大，排数不可近似替代计算。研究可为今后柔性支架多排多跨的近似替代设计提供参考，减轻计算工作量。

Flexible photovoltaic brackets are gradually being widely used in fishery photovoltaic complementary projects due to their large span, few piles, and large adjustment space for ground height. With the increase of project scale, the length and width of a single flexible array can reach several hundred meters. This article models flexible supports with different spans and analyzes their stress changes. The results show that when the number of spans calculated for continuous spans reaches 6, the error of each cable force is within 5% compared to the entire array, which can be used for approximate substitution calculation. However, the cable forces of the reverse arch cable and transverse diagonal cable vary greatly with the number of spans, and the number of spans cannot be approximated as a substitute for calculation. This study can provide reference for the approximate design of flexible supports with multiple rows and spans in the future, reducing computational workload.
