柔性墩是桥梁墩台向轻型化发展的一项新技术,已在我国铁路桥梁上逐步推广应用。有关柔性墩的计算理论、计算方法及其简化也正在进行探讨。本文将工程上(如弹性地基梁、桩基等)常用的初参数法推广应用于柔性墩的静力计算,供有关部门参考。一、墩轴挠曲线的微分方程 Flexible pier is a new technology of bridge piers and light-weight development. It has been gradually popularized and applied in China’s railway bridges. The computational theory, calculation method and simplification of flexible piers are also under discussion. In this paper, the commonly used initial parameter method in engineering (such as elastic foundation beam, pile foundation, etc.) is popularized and applied to the static calculation of flexible piers for the reference of relevant departments. First, the differential equation of the shaft bending curve
