摘要:

为降低装配式建筑项目施工风险,基于事故分析等方法提炼指标,建立5个一级指标、26个二级指标的装配式建筑施工风险评价指标体系;引入变权理论和贴近度替换传统物元可拓方法中的常权赋权法和关联度算法,构建基于改进物元可拓的装配式建筑施工风险评价模型;应用该模型进行案例验证,得出案例工程施工风险等级为1级,属于低风险,并通过对比改进模型与传统物元可拓模型的评价结果,验证改进模型的有效性。结果表明:应用基于改进物元可拓方法构建的装配式建筑施工风险评价模型,可以在事故发生前有效评价项目风险状况,达到提高风险管理效益的目的。

Abstract:

In order to reduce the construction risks of prefabricated building projects, indexes were refined based on accident analysis and other methods, and the construction risk evaluation index system of prefabricated buildings with 5 primary indexes and 26 secondary ones was established. Then, the contingency theory and nearness degree were introduced to replace constant weight assignment method and correlation degree algorithm in traditional matter element extension method, and the construction risk assessment model of prefabricated buildings based on the improved matter element extension was constructed. Finally, the model was applied to validate the case whose construction risk level was obtained to be 1, namely low risk, and effectiveness of the model was verified by comparing its assessment results with those of the traditional one. The results show that the assessment model based on the improved matter element extension method can be applied to effectively evaluate the project risk status before the occurrence of accidents and achieve the purpose of improving risk management benefits.
