摘　　要：随着碳纤维(CFRP)新型复合材料广泛的应用于房屋、桥梁、工业厂房、海洋平台等新建工程及加固维修工程中,国内外对CFRP筋混凝土的研究越来越多,大多数是对简支梁的研究,对CFRP筋连续梁的研究还比较少,但实际工程中大部分梁为连续梁。设计5根碳纤维预应力棱柱体(CFRP-PCPs)复合筋混凝土连续梁进行承载力试验研究,考虑弯矩重分布对连续梁跨中承载力的影响,提出了碳纤维预应力棱柱体复合筋混凝土连续梁极限承载力的理论建议公式。结果显示,理论计算值与试验结果吻合良好,为CFRP-PCPs复合筋混凝土连续梁在工程上的应用提供了较好的理论基础。At present, with the carbon fiber （CFRP） new composite materials widely used in housing, bridges, industrial workshop, offshore platforms, other new engineering and reinforcement of the maintenance works, there are more and more researches on CFRP reinforced concrete at home and abroad. Most of the research is on simply supported beams. And the research on the continuous beams with CFRP tendons is relatively small. However, most of the beams are continuous beams in the actual engineering. Through 5 CFRP-PCPs composite reinforced concrete continuous beam subjected to force performance test to verify the theoretical derivation formula, the results of theo- retical calculation and test results are in good agreement, for CFRP-PCPs composite reinforced concrete continuous beam apply to the construction engineering provides a better theoretical basis.
