摘　　要：长联V形墩刚构桥工程应用较少,千岛湖大桥主桥采用(70+7×105+70+40)m多孔长联V形墩预应力混凝土连续刚构,连续长度达915 m。桥位处常水深为45 m左右,基础采用大直径嵌岩钢管混凝土桩。介绍大桥设计和施工技术中的主要特点和创新。The V-shape pier rigid-frame bridges with long continuous units are not often applied. However, the main bridge of the Qiandao Lake Bridge as presented in this paper is a prestressed concrete continuous V-shape pier rigid-frame structure with multiple spans arranged in （70＋7×105＋70＋40） m and with a continuous unit as long as 915 m. At the site of the Bridge, the constant water depth is about 45 m and the bridge foundations are used with large diameter socketed concrete-filled steel tube piles. In this paper, the major technical features and innovation of the design and construction of the Bridge are dealt with.
