| 摘 要： | 刚构桥施工过程中应力变化复杂,影响因素多,较难预测把握应力发展趋势,实测应力缺失时,单一使用GM(1,1)模型预测精度低,对原始应力数据要求苛刻.文章改进了不等时距GM(1,1)模型,结合罗天乐特大桥工程进行验证,结果表明,改进不等时距GM(1,1)模型在刚构桥施工应力预测中具有较好的适用性和较高的预测精度. |

| Abstract: | Stress variation is complicate during the course of rigid frame bridge construction,it is difficulty to gasp the development trend of stress since too many influencing factors,scope of application and prediction accuracy of GM(1,1)model is low,data requirement is too high.modified equal interval GM(1,1)is a improvement to GM(1,1)model of deficiency and distortion stress,which is verified through engineering example of Lu Tian-le Bridge,and modified equal interval GM(1,1)exhibit the abroad applicability and high precision of prediction. |
