摘要
介绍了确定斜拉桥合理施工状态的正装迭代法,该方法运用最小二乘法原理,根据合理成桥状态,通过正装迭代计算,求出各施工状态的张拉索力和立模标高,克服了倒拆法的一些弊端,有效地解决了结构的非线性问题。
The forward iteration method for determining rational construction state of cable stayed bridges is introduced in the paper. It can deduce the cable tensile forces and the form setting levels of every construction state by method of least squares, according to the rational dead load state. Some disadvantages of backward analysis method are avoided and nonlinear problems of structure are solved effectively.
