摘　　要：与传统桥梁简洁之美不同的是当代景观桥之美更多是以繁多曲线、高低错落、平纵不对称等复杂构造来表现。在结构上常表现为力学特性非线性、不对称等特点,故给设计、计算和施工等方面都带来了更大的挑战。通过详细介绍小曲率半径大悬挑景观人行桥的基本情况、设计特点及计算过程,以期供同类桥梁工程提供参考。Unlike the simple beauty of traditional bridges,the beauty of contemporary landscape bridges is more expressed through complex structures such as numerous curves,staggered heights,and bidirectional asymmetry.In terms of structure,it often exhibits mechanical characteristics such as nonlinearity and asymmetry,which pose greater challenges in design,calculation,and construction.This study provides a detailed introduction to the basic situation,design characteristics,and calculation process of a small curvature radius large cantilever landscape pedestrian bridge,for reference by similar bridges.
