建设项目职业病危害预评价类比数据库设计及优选类比对象

Design of Occupational Hazard Pre-Evaluation Analog Database for Construction Projects and Analog Objects Priority

  • 摘要:
    目的 鉴于目前建设项目职业病危害预评价采用类比法时面临的类比对象难以选择的问题,通过本研究设计建设项目类比数据库,用以优选类比对象,提高类比推断的可信性。

    方法 根据积累的建设项目职业病危害评价资料建立类比数据库,通过查询,快速找出符合要求的类比对象,再应用统计学均衡性检验原理优选。

    结果 通过实例说明优选过程,首先应用条件查询筛选出符合类比要求的两个项目,再利用统计学均衡性检验原理(P > 0.05)优选出最适合的类比对象。

    结论 应用类比数据库查询类比对象,再用统计学原理优选,对提高预评价工作质量具有重要意义。

     

    Abstract:
    Objective To solve the problems in selecting analog objects for occupational hazard pre-evaluation in construction projects by establishing an analogy database of construction projects to prioritize analog objects and improve analog deduction reliability.

    Methods Based on the accumulation of occupational hazard evaluation data, an analog database was established and used to identify analog objects meeting selected requirements. Statistical balance test on objects selecting was performed.

    Results The prioritized objects selection was explained by an example. A balance test was applied to the most appropriate analogy objects which were identified by a query filter in two projects using the established database (P > 0.05).

    Conclusion Prioritized selection using analog database querying in combination with statistical principle can improve the quality of pre-evaluation of occupational hazards in construction projects.
