摘要
本文从人员、材料、机械、管理、技术和环境风险六个方面,共计23个评价指标来建立装配式建筑施工安全风险评价指标体系。采用物元可拓模型并引用熵权法计算指标权重,从而建立熵权物元可拓模型评价装配式建筑施工。结果表明:合肥某装配式该项目总体等级处于Ⅱ级,属于较安全状态,其中管理、机械、材料、环境风险等级为Ⅱ级,属于较安全状态,但是其人员危和技术风险等级为Ⅲ级,属于一般状态,对其安全影响较大。
In this paper,a safety risk evaluation index system with total 23 evaluation indicators for prefabricated building construction is established from six aspects of personnel,material,machinery,management,technology and environmental risk.The matter-element extension model is adopted and the entropy weight method is used to calculate the index weight,so the matter-element extension model with entropy weight is established to evaluate assembly building construction.The results show that the overall level of an assembly type project in Hefei is atⅡlevel,which belongs to a relatively safe state.The risk level of management,machinery,materials and environment is at IIt level,which belongs to a relatively safe state.However,the risk level of personnel and technical risk is at III level,which belongs to a general state,and has a great impact on its safety.
