以114名土木工程专业本科生的13门课程成绩为样本，应用SAS软件分别进行正态性检验、线性相关分析和主成分分析，认为结构力学、混凝土结构设计和高等数学等课程成绩最能代表该专业学生的总体学习效果，并对改进土木工程专业的教学工作提出了建议.

With a sample of 13 course scores of 114 students majored in civil engineering, statically analysis such as normality test,linear correlation analysis and principal component analysis was applied via SAS system. It was held that structural mechanics,concrete structure design and higer mathematics are the most important courses for civil engineering majored students.Improved recommendations for civil engineering education were also proposed.
