一、中小桥结构轻型化的出发点传统的重力式桥墩台均系利用自身重量稳固在地基上,形成似悬臂梁式的受力状态,计算时每个墩台都按单独受力结构考虑。本文叙述的直线上中小桥结构轻型化 First, the light weight of the bridge structure of the starting point of the traditional gravity bridge piers are using their own weight and stability in the foundation, forming a cantilever-like state of force, the calculation of each piers are considered by a separate force structure. This article describes the light on the small bridge structure
