| 摘 要： | 对拱坝温度进行实时监控对工程进度和坝体安全具有重要意义.基于灰色系统理论,利用最小二乘法确定GM(1,1)白化权函数的时间响应函数中的常数C,从而构建GM(1,1)的时间响应函数的最优模型,用MATLAB语言编制程序预测模型,并以白莲崖拱坝温度监测数据为例进行分析、预测.结果表明,这种方法能较好地应用于小数据量监测数据的预测,且精度较高. |

| Abstract: | Temperature monitoring for arch dams is very important in engineering construction,as well as for dam safety.Based on the gray system theory,the paper utilizes the method of the least square estimate to find the constant number C in the time response sequence of whiterization equation of GM(1,1),then creates the optimum model for the time response sequence of whiterization equation for GM(1,1),sets up a forecasting model by means of MATLAB to simplify calculation,and analyzes the monitoring data of Bailiany... |
