摘要
针对建筑施工中对高风险行为存在定位不准和结果多元,即自适应监测的匹配度和灵敏度低等问题,提出一种基于结构方程的建筑施工高风险行为自适应监测方法;根据建筑施工高风险行为预应力结构因子的权重矩阵、高风险行为的适应度函数构建风险预估函数,形成结构方程模型;采用t规则识别方法及最大似然法,完成对结构方程模型的识别及拟合,根据拟合优度评价指标完成结构方程模型修正;将修正好的结构模型转换为结构方程,实现建筑施工高风险行为高灵敏度自适应监测。结果表明,提出的方法的监测灵敏度为99%,监测自适应匹配度为98.75%,监测灵敏度和匹配度均得到了很大程度的优化。
Aiming at problems of inaccurate positioning and multiple results of high risk behaviors in building construction,that is,low matching degree and sensitivity of adaptive monitoring,an adaptive monitoring method of high risk behaviors in building construction based on structural equations was proposed.According to the weight matrix of prestressed structural factors and the fitness function of high risk behaviors in building construction,the risk prediction function was constructed to form the structural equation model.The t-rule recognition method and the maximum likelihood method were used to complete identification and fitting of the structural equation model,and the structural equation model was modified according to goodness of fit evaluation indexes.The modified structural model was transformed into a structural equation to realize high risk behaviors and adaptive monitoring with high sensitivity of building construction.The results show that the monitoring sensitivity of the proposed method is 99%,and the adaptive matching degree is 98.75%.The sensitivity and matching degree of monitoring are optimized to a great extent.
