摘　　要：通过对复合墙板构成材料纤维混凝土干燥收缩率和热膨胀系数的实际测试,研究分析了复合墙板在干燥阶段和使用过程中由于含水率变化而引发的变形行为,以及复合墙板在使用过程中经历不同季节温度变化时所引发的变形行为,并为减缓这种不利的变形行为提出一些技术控制措施。Through testing on drying shrinkage and thermal expansion coefficient of fiber reinforced concrete,we studied and analyzed on deformation behavior of the sandwich wall panel caused by moisture content change during drying phase and the application period,we also studied and analyzed on deformation behavior of the sandwich wall panel caused by temperature change in different season during the application period,and we suggest some technical measures for reducing such unfavorable deformation behavior.
