摘　　要：采用CSS-WAW-1000DL电液伺服万能压力试验机,进行自密实混凝土棱柱体试件单轴受压试验。对自密实混凝土应力-应变全曲线进行分析,给出了自密实混凝土的应力-应变全曲线方程。结果表明:自密实混凝土应力-应变关系曲线与普通混凝土应力-应变关系曲线基本相似,但各特征点的位置有所变化;根据自密实混凝土应力-应变全曲线方程作出的计算曲线与试验曲线吻合较好。Tests were carried out to research self-compacting concrete prismatic specimen under uniaxial compression by using CSS-WAW-IOOODL rock testing machine. The complete stress-strain theoretical curve equations were proposed by analyzing the complete stress-strain curves of self-compacting concrete. The test results showed that the stress-strain curves of self-compacting concrete were similar to the stress-strain curves of ordinary concrete, but the location of the feature points changed; and the calculated stress-strain curves by the complete stress-strain theoretical curve equations were in good agreement with the test stress-strain curves.
