摘　　要：成功地测出了钢纤维膨胀混凝土管状试件轴拉应力 -应变全过程曲线 ,并应用微裂缝开展理论 ,对全过程曲线作了宏观过程和微观机理分析 .在试验基础上 ,对钢纤维膨胀混凝土管状试件受拉应力 -应变全曲线进行了数值模拟 。The axial\|tension stress\|strain full curves for the member of the steel fiber reinforced expansive concrete are measured successfully .The macroscopical progress and the micro\|mechanism of the curves have been analyzed by the micro\|cracking extension theory .Based on the test results, the numerical simulation for the stress\|strain full curve has been carried out. The simulation equations are given, which show good agreement with the experimental results.
