【摘要】 本文针对南水北调中线输水建筑物渡槽工程中使用的一种高性能复合纤维与细灰增强混凝土,基于多批压缩试验测定的压力与变形、压应力与应变的试验结果,以及受压时应力与应变全曲线性状,提出了描述受压应力与应变全曲线性状的相应数学模式,为进行配筋特种混凝土渡槽设计与数值计算,提供了材性和力学分析方面的理论基础。更多还原

【Abstract】 This paper aimed at the high performance compound fiber and detailed dust strengthened concrete that is applied to water building aqueduct project of the centre line of South-North Water Diversion, on the basis of the results of the pressure-deformation and compressive stress-strain that were measured by a list of compressed tests, at the same time based on the corresponding mathematical mode of the complete compressive stress-stain curve, this offered theoretical foundation on the material property and the analysis of mechanics for design and numerical solution of the reinforced concrete structure.更多还原
