摘　　要：拟修建的巴卡尔桥为432 m跨径的拱桥,位于里耶卡到塞尼的高速公路上,横跨巴卡尔海峡。该桥几乎完全由强度达到200 MPa的活性粉末混凝土预制构件拼装组成。对该桥新颖的结构形式,施工工艺和富有美感的外形进行了描述与分析。The Bakar Bridge to be built on expressway from Rijeka to Senj and over the Bakar Straits is a 432-m span arch bridge composed of almost all precast and assembled reactive powder concrete elements with concrete strength up to 200 MPa. In this paper, the novel structural type, construction technology and graceful configuration of the Bridge are described and analyzed.
