| 摘 要： | 为了克服施工现场安全评价中存在的主观性强、不易处理高维数据的缺陷,提出了基于投影寻踪模型施工现场安全评价的新方法.该方法利用遗传算法实现了投影寻踪技术,将样本的多维评价指标值投影为一维投影数据,并据投影值大小确定各现场的安全程度.工程应用实例表明,该模型易于评价,具有很强的客观性、适用性和可操作性,为施工现场安全评价提供了新的技术工具.

| Abstract: | To overcome the shortcomings of the safety evaluation of the construction building sites,an evaluation model for the construction plan based on projection pursuit(PP) was presented.The genetic algorithm was employed to realize the projection pursuit.And the values of the evaluation index were synthesized into a one-dimension projection value which was used to finish the plans.The genetic algorithm was employed to realize the projection pursuit.And the values of the evaluation index were synthesized into a one-dimension projection value which was used to finish the plans.Engineering practice shows that the method can realize the assessment simply,objectively and feasibly.This work has significance for the evaluation of the safety on building sites. |
