轻型悬索桥的调查与分析

Investigation and Analysis for Light Suspension Bridge

轻型悬索桥在我国的河谷山涧地区以及城市人行桥中应用较广泛,但对其结构设计特点尚未有较系统的总结。文中在大量收集国内已建轻型悬索桥资料的基础上,从桥跨、加劲梁以及主索等方面分析总结其设计特点,包括轻型悬索桥的适用跨径、桥跨布置特点,加劲梁的截面形式、高跨比,主索材料、垂跨比和锚固形式等。

Light suspension bridges were constructed widely at valley and mountain stream and pedestrian bridge in cities in our country.But at present,there is no system summary in the main structure design features of the bridge.In this paper,plenty information about light suspension bridges are collected.And the structure design features was analyzed and summarized from the span,stiffening girder,main cable and so on,which includes the reasonable span,the characteristic of bridge span,the section form of stiffening girder,the height-to-span ratio and the materials,the drag-span ratio and the anchorage form of main cable.
