回归预测法在桥梁剩余寿命预测中的应用研究

随着公路交通事业的发展，在役桥梁的使用状态越来越引起了人们的广泛重视．准确地预测在役桥梁的剩余使用寿命可为公路管理部门的养护维修方案提供可靠的决策依据，节省了建设资金，保障了桥梁的安全．但到目前为止，该方面的研究进展比较缓慢．提出了引入回归预测这一数学原理对该问题进行研究分析，方法简单适用，并孳用实例加以说明，实现了桥梁结构剩余使用寿命的预测．

Application of Regression Forecast to Bridge Residual Life

With the development of the road communication, the state of the used bridges have been paid more attention. If the residual life of the used brideges can be properly forecasted, the road management department will make a reliable decision about the maintenance of the used bridges. This can not only save the money, but also ensure the safety of the bridges. But by now, the study on the problem is still very slow. This paper puts forward the regression forecast method to analyze and study the problem. The method is simple and usable. Finally, the paper gives an example to illustrate it.
