摘要:
为降低不确定信息对装配式建筑施工中高处坠落风险评价的影响,针对我国当前装配式建筑施工特点,构建了基于改进证据理论的装配式建筑施工高处坠落风险评价模型.通过实地调研及专家咨询,从人、物、环境、管理四个维度建立了装配式建筑施工高处坠落风险评价指标体系.在此基础上,采用结构熵权法确定指标权重.基于权值分配与矩阵算法对DS证据理论合成法则进行改进,利用改进后的证据理论评价装配式建筑施工中高处坠落风险.通过对该模型进行实证研究,结果表明,该风险评价模型能解决高冲突证据融合结果不合理的问题,具有较高的有效性和实用性,可为预防装配式建筑施工中的高处坠落事故提供决策支持.
Abstract:
In order to reduce the impact of uncertain risk information on the assessment of the risk of falling accidents in prefabricated building construction, a risk assessment mode for falling accidents in the construction of prefabricated buildings based on improved evidence theory was constructed according to the current characteristics of prefabricated building construction in China. Through field research and expert consultation, an index system for the assessment of falling risk in prefabricated building construction was established from the four dimensions of human, material, environment, and management, and on this basis, the weight of each index was determined by the structural entropy weight method. Then, based on the weight distribution and matrix algorithm, the synthesis rule of DS evidence theory was improved, and the improved evidence theory was used to evaluate the risk of falling accidents in the construction of prefabricated buildings. The empirical study of the model shows that the risk assessment model can solve the problem of unreasonable results of high conflict evidence fusion, thus having high effectiveness and practicability, which can provide decision support for the prevention of falling accidents in the construction of prefabricated buildings.
