摘　　要：对碳纤维水泥砂浆梁的电热效应及其所引起的热力变形进行了实验分析,得到了梁的升温规律和变形发展规律,找出了梁的上下表面稳定温差及最大变形与输入功率的关系,从而为梁的变形调节提供了实验依据.The electrothermal effect and the thermodynamical effect of carbonfiber cement mortar beam were studied by experiment. The curves of temperature variation of the beams with electrified time and the deformation development curves were obtained. The relation between the stable temperature difference, maximum deformation and input electric power were found. The test results of this paper could provide experimental basis for deformation adjustment of carbonfiber cement mortar beams.
