基于因子分析法的建筑工程设计风险因素实证研究

Empirical Research of Construction Engineering Design Risk Factors Based on Factor Analysis

为提高建筑工程设计风险的评价和管理水平,减少因建筑工程设计质量差引发安全事故,为此找出建筑工程设计的关键风险因素,并研究其风险评价和管理的方法。在分析相关文献的基础上,通过问卷调查的方式,归纳总结出33个建筑工程设计风险因素;再结合问卷调查结果,采用因子分析法,利用SPSS统计软件计算,从33个建筑工程设计风险因素中,提炼出具有代表性的8个公共因子,同时得到各个因子的影响作用情况。最后,结合各因子得分矩阵,得到建筑工程设计风险的计算函数,用以计算评价不同建筑工程设计项目的综合风险。

In order to improve the level of risk evaluation and management on construction engineering design,and reduce safety accidents due to poor quality of building design,key risky factors of construction engineering design must be found out and its risk assessment and risk management method must be studied.Based on related literatures and questionnaire survey,33 risk elements affecting construction engineering design are summarized.SPSS statistical software is used to calculate the result obtained by questionnaire survey.Then 8 public factors are extracted from the 33 risk elements by using Factor Analysis method,and the influences of each factor are obtained.Finally,combining with each factor score matrix,the computation function of construction engineering design risks is gotten,which is used to calculate the comprehensive risk of different engineering projects.
