Design of Pedestrian Glass Suspension Bridge in a Scenic Area

摘要:

人行玻璃悬索桥是一种较为新颖的桥型，具有外形美观、构造简单和受力明确的特点，又因其出色的视觉体验增添了旅游价值，在诸多旅游景点得到了应用。介绍了一座主跨36 m的平行索面人行玻璃悬索桥，主缆垂跨比为1/7.2，采用重力式锚碇，桥塔使用拱形钢管结构，加劲梁采用纵横梁格构体系，格构的露空部分铺设超白钢化夹胶玻璃。详细介绍了此桥的总体设计、细部构造和施工流程，并列出了主要的计算结果。该桥造型简洁，无需设置抗风缆索，适应性强，在中小型景区中有较大的推广价值。

Abstract:

Pedestrian glass suspension bridge is a relatively novel bridge type, which not only has the characteristics of beautiful appearance, simple structure and clear force, but also increases the tourism value because of its excellent visual experience and has been used in many tourist attractions. A parallel cable-plane pedestrian glass suspension bridge with a main span of 36 m is introduced. The vertical span ratio of the main cable is 1/7.2, and the gravity anchorage is used. The bridge pylon is made of arched steel pipe structure, and the stiffening beam is a longitudinal and transverse beam lattice system. The exposed part of the lattice is paved with ultra-white tempered laminated glass. The overall design, detailed structure and construction process of this bridge are introduced in detail, and the main calculation results are listed. This bridge has a simple and elegant design without the needs for installation of wind-resistant cables, and its adaptability is strong, making it highly valuable for promotion in small and medium-sized scenic spots.
