摘　　要：施工过程监测数据由趋势项、周期项、随机项等效应耦合组成,为提取出对施工过程质量安全具有指导意义的趋势项,提出了一种基于滑动平均法的施工过程监测数据解耦方法。采用数学方法构造离散时域信号,根据趋势项和其他项变化速率的不同来过滤周期项和随机项,从而解耦得到趋势项。通过对某超限高层工程实例施工过程的研究,对监测数据进行解耦分析,提取得到趋势项,验证了该方法解耦监测数据的高效性和适用性。The construction process monitoring data is composed of trend term,periodic term,random term and other coupling effects.In order to extract the trend term which has guiding significance for construction process quality and safety,a decoupling method of construction process monitoring data based on moving average method is proposed.The discrete time domain signal is constructed by mathematical method,and the periodic term and random term are filtered according to the change rate of trend term and other terms,so the trend term is decoupled.Through the research on the construction process of an overlimit high-rise project,the decoupling analysis of monitoring data is carried out,and the trend term is extracted,which verifies the efficiency and applicability of the decoupling monitoring data.
