摘　　要：在建筑领域,当前的建筑混凝土粘性估计方法不能准确描述冷热分布不均匀环境下粘性的变化,获取的结果存在较大的偏差。为了解决这一问题,提出一种建筑混凝土粘性与温度变化的测试分析模型,分析了建筑混凝土粘性随温度变化的趋势,通过温度载荷波动曲线对冷热分布不均匀环境下的建筑混凝土粘性的时变进行测试分析,采用修正因子强化当前测试数据的价值度,过滤无价值数据的干扰,使用渐进最小二乘算法计算粘性大小。实验结果说明,所提方法对不同温度条件下的建筑混凝土进行粘性估计具有较高的稳定性和鲁棒性,具有很强的应用前景。Put forward a kind of architectural concrete viscosity and temperature change test analysis model, analyzed the construction of concrete viscosity with temperature changing trend, through the temperature curve of load fluctuation on the uneven distribution of cold and hot sticky time-varying environment building concrete test analysis, the correction factor to strengthen the degree of the value of the current test data, interference filter useless data, gradual least-square algorithm is used to calculate viscosity size. Experimental results indicate that the proposed method for construction of concrete under different temperature conditions is used to estimate viscosity has high stability and robustness, has a strong application prospects.
