摘　　要：将精细积分与传递矩阵法相结合,提出一种新的精细传递矩阵格式,应用于曲线桥的分析中。与传统的传递矩阵法相比,无需对微分方程组进行求解,只需迭代即可得到所需要的传递矩阵。根据边界条件,得到结构的内力及变形。算例表明,该方法正确有效。By combining the high-precision precise integration and the transfer matrix method, a new precise transfer matrix form is derived and applied to solve the structure analysis of the curved bridge. Compared with the traditional transfer matrix method, there is no need to solve the differential equations, and just by following the iterative formulae one can get the corresponding transfer matrix. According to the boundary conditions, the deformation and the internal force of the structure can be obtained. Example shows that the method is effective.
