摘　　要：利用传感器法测试了青岛体育中心综合训练馆预应力梁的孔道摩擦系数,根据测试结果知道该工程预应力梁的孔道摩擦系数k=0.001 5,μ=0.541,同时对张拉和拆模过程中预应力梁的支座和跨中截面的应力进行了测试,并与计算值进行对比,两者较为接近。This paper had tested the channel friction coefficients of the prestressed beams of Qingdao sports center integrated training stadium by using load cell method. According to the results that the channel friction coefficients of the prestressed beams in this project were k = 0. 001 5, μ = 0. 541. Meanwhile, the prestress of prestressed beams＇ bearing and mid-span section while tension and form removal were tested. The results were compare with calculated value, the two were close.
