The impacts of material spatial variability were usually not considered in traditional slope stability analyses. However, most geotechnical materials are usually not uniform inside a slope. Thus, traditional ways of analyses were not very reasonable. On the other hand, most geological explorations used vertical borings. Horizontal and inclined borings were seldom performed unless required by the client.

摘要 传统边坡数值稳定性分析时，大多没有考虑到材料空间变异性之影响性，材料无论在理论上或是在实际边坡上很少边坡为均质材料，因此传统的边坡分析是种较为不合理的现象，而地质钻探时都是以垂直钻探为主，除试验需要外，极少以水平或倾销钻探作为设计之基础，这也与现地所需有关系，导致空间变异性资料难以取得必需以现地资料加上文献中提及的尺度变动作为分析依据。

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。
