In order to improve the high-performance concrete quality of longer brittleness, lower tensile strength, particularly the less descending branch in stress-strain curve compared with that of ordinary concrete. The breakthrough of this thesis lies in the mixture of short carbon fiber. Four factors such as water-binder ratio, volume ratio of short carbon fiber and blending value of high efficiency water-reducing admixture were selected as variable. Experiment was carried out by utilizing uniform design. Regression equation was established by regression analysis of the compression strength and the split tensile strength separately utilizing SPSS software. The process of optimization was obtained with the aid of MATLAB. Finally the optimized ratio was acquired.

为了改善高强混凝土由於水泥自缩、湿涨造成的脆性大、抗拉强度低，特别是应力－应变曲线的下降段不及普通混凝土的特点，本文以掺入短碳纤维为突破口，选取水胶比、砂率、短碳纤维的体积比、高效减水剂掺量四个因素作为变量，利用均匀设计安排试验，用SPSS软件对抗压强度和劈拉强度分别进行回归分析而得到回归方程，用MATLAB进行优化处理，进而求出最优配比。

The electropinning parameters (voltage, concentration and C-SD) influenced the mechanical properties of electrospun nylon 6 fiber mats. With increase of the solution concentration, the breaking stress and strain of the mat became large. The effect of C-SD was contrary. The nylon 6 fiber mat electrospun on the high voltage had low elongation but high strength.
