摘要
为了确保震后高层建筑坍塌墙体修复工程的安全性,提出一种高层建筑震后坍塌墙体修复施工安全管理方法。结合主成分分析法与信息熵法对震后高层建筑坍塌墙体修复施工管理的控制特征量进行提取,确定模型评价指标权重;根据加权学习法对坍塌墙体修复的施工进行量化控制;通过灰阶量化评估进行约束参量分析,构建安全管理控制模型;采用管理因素模糊调度算法实现施工安全管理控制,并完成优化决策。通过仿真实验验证坍塌墙体修复施工管理控制的管理效益与累积评价百分率。分析结果表明,采用该方法进行震后高层建筑坍塌墙体修复施工管理控制的管理效益最高可达83.32%,累积管理效果回报率较高,累积评价百分率平均约为75%,能够有效提高施工过程的安全管理效能,确保施工安全。
To ensure safety during the process of repairing of collapsed walls of the high-rise buildings after an earthquake,some safety management guidance measures are given.In addition,a safety management method for repair of collapsed walls of high-rise buildings after an earthquake was proposed.Combined with principal component analysis and information entropy method,the controlled characteristic variables for the repair of collapsed wall of high-rise buildings post earthquake were extracted to determine the weight of the model evaluation index.The quantized control for the management of collapsed wall restoration based on weighted learning method was conducted.A security management control model was constructed by constrained parametric analysis through grayscale quantitative evaluation.The construction safety management control was realized by adopting the fuzzy scheduling algorithm and the optimization decision was completed.The management benefit and cumulative evaluation percentage for the restoration construction management control for the collapsed wall were verified via simulation experiments.The case analysis results showed that the management benefit of this method can reach 95.34%,and the cumulative evaluation percentage was about 98.65%.The method can considerably improve the safety management efficiency of the construction process and ensure construction safety.
