摘要
矮塔斜拉桥(又称部分斜拉桥)主要塔矮、梁刚、索集中的特点;在外观上类似普通斜拉桥,而在受力区别与施工技术方面,它更接近连续刚构(连续梁)桥,大桥造型美观、造价经济合理。本文以主跨65m+108m+65m双塔单索面三跨预应力混凝土矮塔斜拉桥为工程背景,同时为矮塔斜拉桥的施工技术进行部析,为以后类似工程提供参考经验。
Short-pylon cable-stayed bridge （ also know as partial cable-stayed bridge） is mainly characterized by low tower, Liang Gang and cable concentraction. It similiar to ordinary cable-stayed bridge in appearance, but it is more close to the continuous steel structure bridge （continuous brigde） in the stress difference and construction technology. The bridge has beautiful appearance and with reasonable cost of construction.
