滑动平均法在刚构桥施工应力预测中的应用

Application of Sliding Average Method in Stress Prediction for Rigid Structure Bridge

文章针对刚构桥施工过程中应力不确定性影响因素,介绍通过滑动平均法GM(1,1)模型对数据进行建模前预处理方法,并结合葫芦鼎大桥工程实例,验证了滑动平均法建立GM(1,1)模型在刚构桥施工应力预测中较好的适用性和较高的预测精度,也是对原始GM(1,1)模型的一种改进。

Aiming at the stress variation during the construction of rigid structure bridge,the Paper presented the data pre-treating method that adopts sliding average method GM(1,1)model.With Huluding Great Bridge as an example,it proved that the GM(1,1)model established by sliding average method can have better adaptability and higher precision in stress prediction during rigid structure bridge construction.Such method also improved the primary GM(1,1)model.
