摘要
连续刚构桥预拱度可分为施工预拱度和成桥预拱度。对于成桥预拱度的设置问题,目前通常的计算方法原理不清晰,且随意性较大。为了有效地克服了通常算法的不足之处,本文提出了一种正交多项式拟合法去计算成桥预拱度,并通过一座实桥的成桥预拱度分析,验证了该法的可靠性。
ontinuous rigid frame bridge pre-camber can be divided into construction of pre-camber and bridge pre-camber.However,the principle of the usual method which used to set bridge pre-camber,is not clear but arbitrary.In order to overcome the deficiency of usual algorithm effectively,this paper raises a orthogonal polynomials＇ fitting method.As a result,the reliability of this method has been verify through the analysis of bridge camber of a real bridge.
