摘　　要：介绍了大连市金州湾二桥主桥的三个设计方案,即预应力混凝土斜拉桥方案、自锚式悬索桥方案、自锚式斜拉-悬索协作体系桥方案。分别从施工难易程度、经济适用性和外观造型等方面进行综合比较分析,认为自锚式斜拉-悬索协作体系桥方案最适合在此处实施,推荐其为本工程的首选方案。The paper introduces three design schemes for Er Bridge＇s main bridge in Dalian City＇s Jinzhouwan： scheme for cable stayed bridge of prestressed concrete ; scheme for self - anchored suspension bridge; and scheme for combined hierarchy of self - anchored cable - stayed bridge with self - anchored suspension bridge. From difficult and easy extent in construction, economic applicability and appearance modelling ect,the paper considers that the combined hierarchy -scheme is most suited for implementation here, so recommended as the first scheme selected.
