摘　　要：对3组共9个水泥混凝土棱柱体试件(150mm×150mm×300mm)进行逐级加载试验,研究水泥混凝土棱柱体试件轴心受压时接近试验机压头位置以及其他各截面纵向应变的分布状况,得到不同荷载作用下的各截面应变分布曲线。分析水泥混凝土棱柱体试件不同位置在荷载逐渐加大情况下的应变分布规律,进而得到应变分布曲线方程。Loading test was carried out for a total of nine cement concrete prism specimens （ 150 mm × 150 mm × 300 mm） in three groups to get distribution status of the prism longitudinal strain at sections close to the tesing machine and other sections under axial compression. Strain distribution curves of all the sections under different loads were obtained. The distribution law of strain at different locations of the prism was analyzed when the load gradually increased, and then the equations of these strain distribution curves were established.
