摘　　要：对于预应力混凝土梁的施工而言,孔道摩阻是造成预应力损失的重要因素之一。文中对现浇预应力混凝土简支梁进行孔道摩阻试验,对试验结果进行分析,并与相关规范值及设计值进行对比,对后续正确指导现浇预应力简支梁施工及预应力张拉工作提供参考。For the construction of pre-stressed concrete beams,duct friction is one of the important factors that cause pre-stress loss.In this paper,the duct friction test of cast-in-place pre-stressed concrete simply supported beam is carried out,and the test results are analyzed and compared with the relevant specifications and design values;It can be used as a reference to correctly guide the construction of cast-in-place pre-stressed simply supported beams and pre-stressed tensioning.
