摘要
装配式建筑施工过程要在多维空间中进行,叠加风险高,事故发生率高于传统现浇建筑施工,因此科学、准确地测度装配式建筑施工风险具有重要的现实意义.根据装配式建筑施工的特点,从人员、机械、环境、技术、管理5个维度建立了装配式建筑施工风险测度指标体系,并构建了相关系数-熵-二维云风险测度模型.实例应用结果表明:该测度模型较全面、客观、准确地反映了装配式建筑施工风险要素,能够有效实现装配式建筑施工过程风险的定量化测度,可为装配式建筑施工安全管理提供有力参考和依据.
Abstract
The construction process of prefabricated building projects should be carried out in multi-dimensional space,with high superposition risk and higher accident rate.Therefore,it is of great practical significance to measure the construction risk of prefabricated building scientifically and accurately.According to the characteristics of pre-fabricated building construction,this paper established the risk measurement index system of prefabricated building construction from five dimensions:man,machine,environment,technology and management,and constructed the correlation coefficient—entropy—two-dimensional cloud risk measurement model.The result shows that the mea-surement model is comprehensive,objective and accurate to reflect the risk factors of prefabricated building con-struction,and can effectively realize the quantitative measurement of the risk of prefabricated building construction process,and provide a strong reference and basis for the safety management of prefabricated building construction.
