矮塔斜拉桥的结构特点和工程质量控制研究

Structure Features and Engineering Quality Control of Low-Pylon Cable-Stayed Bridge

矮塔斜拉桥是介于斜拉桥和连续梁(刚构)桥之间的组合桥型,兼具斜拉桥的纤细柔美和连续梁(刚构)桥的刚劲有力,是一种刚柔互补型的桥梁。随着我国基础建设的快速发展,国内的矮塔斜拉桥也越来越多。通过介绍矮塔斜拉桥的结构特点来反映矮塔斜拉桥的优势,并以平顶山市湛河一桥主桥的施工为例,论述矮塔斜拉桥的施工质量控制,以期为同行提供参考和借鉴。

Low-pylon cable-stayed bridge is hybrid structure, which mechanic cnaractc~~ ble-stayed bridge and continuous beam bridge. It is both soft and slender like cable-stayed bridge, and vigorous and effective like continuous beam bridge, so it is complementary rigid-flexible. With the development of the na- tional infrastructure, this bridges structure has more application in recent years. This paper describes the struc- ture features to reflect the advantages of low-pylon cable-stayed bridge, and states the control of construction quality combined with the example of Zhanhe Bridge in Pingdingshan City in hope of providing reference for peers.
