摘　　要：索塔结构既作为缆索支承桥梁的主要承重结构,又是体现其整体景观的重要构件。索塔设计不仅要注重其结构类型的选择及满足受力要求,同时还应重视其造型、断面形状、外观色彩等景观设计。目前,悬索桥的索塔基本上都是H型,斜拉桥的索塔大致分为A型塔、H型塔和独柱塔三种类型,索塔塔柱截面大部分为矩形,塔柱表面大多数为平面。虽然结构简洁,但造型单一,立体感不强,缺少美学艺术特性。结合现有常规斜拉桥及悬索桥的索塔造型,提出一种A型扭转索塔设计方案,使索塔在满足结构受力的同时,又能赋予索塔特有的美观和更丰富的艺术造型。As the pylon has been not only the main load-bearing structure of cable supported bridges, but also the mostimportant component reflecting the overall landscape, the design should not only focus on the selection of structure typesand meet the requirements of force, but also should pay attention to its landscape design of shape, section shape andappearance of color. At present, the pylon of suspension bridge adopts basically type H, while the pylon of cable-stayedbridge can be divided into three types, including type A, type H and single pylon, with the pylon section being mostlyrectangular and pylon surface being plane. Although the structure is simple, the shape is single, the three-dimensionalsense is not strong, being lack of aesthetic artistic characteristics. Based on existing pylon types of conventional cable-stayed bridges and suspension bridges, a design scheme of a torsional pylon has been put forward to make the pylon notonly satisfy the structural force, but also being endowed with unique beauty and richer artistic modeling.
