钢绞线因其高强度、低松弛的特点被广泛运用。本文通过具体事例，对后张法预应力钢绞线伸长值的计算与分析做了阐述，并借助具体公式推算和总结出了伸长值的阙值，希望对行业发展有所帮助。
鋼絞線因其高彊度、低鬆弛的特點被廣汎運用。本文通過具體事例，對後張法預應力鋼絞線伸長值的計算與分析做瞭闡述，併藉助具體公式推算和總結齣瞭伸長值的闕值，希望對行業髮展有所幫助。

Steel strand is widely used because of the charac-teristics of high strength, low relaxation. Through specific ex-amples, this article expounds calculation and analysis of elon-gation value of post-tensioned prestressed steel strand, and then calculates and sums up the threshold of the elongation with the help of specific formula, which is hoping a bet er industry development.
