（深圳市大亞灣核電站華興公司 518124）[提要] 選定鋼束進行摩擦系數(shù)試驗，根據(jù)鋼束的伸長值及被動端的壓力值計算出鋼束與管道間的摩擦系數(shù)，并將此摩擦系數(shù)與設(shè)計的摩擦系數(shù)進行比較，最終確定鋼束的摩擦系數(shù)與伸長值的設(shè)計值。
[關(guān)鍵詞] 鋼束 張拉 摩擦系數(shù) 伸長值 張拉力Selecting typical steel cables to test,the friction factor between the cable and the tube is calculated based on the stressing force in passive end and elongation value of each cable. The design value of friction factor and elongation are defined by comparing the value calculated in test with the value of design.
Keywords: strand; stressing; friction factor; elongation; stressing force
