摘    要:通过对素混凝土和高密度聚乙烯(HDPE)管混凝土的轴压应力应变曲线的计算,得到了延性和韧性的表征参数--延性系数和应变能;研究了管壁厚度、核心混凝土强度对HDPE管混凝土延性和韧性的影响.结果表明,HDPE管混凝土的延性和韧性均远大于素混凝土,并随管壁厚度的增加显著提高;核心混凝土强度的增大只能有限提高HDPE管混凝土的韧性,并且会大大降低HDPE管混凝土的延性.

关 键 词:HDPE管混凝土  塑管混凝土  延性  韧性  轴压应力应变曲线

Abstract:Ductility ratio and strain energy that are regarded as the characteristic parameters of ductility and toughness were calculated from axial stress-strain curves of plain concrete and HDPE-pipe concrete.Effect of pipe thickness and core-concrete strength on ductility and toughness of HDPE-pipe concrete was studied.The results indicate that the ductility and toughness of HDPE-pipe concrete is much better than those of the plain concrete.The increase in pipe thickness can enhance the ductility and toughness of ...
Keywords:HDPE-pipe concrete  plastic pipe concrete  ductility  toughness  axial stress-strain curves
