山东济宁如意洸府河大桥主桥采用（60＋80＋320＋80＋60） m支座体系混合式结合梁斜拉桥。该桥边跨采用混凝土边主梁，中跨采用钢小边箱结合梁，桥塔采用 H形混凝土塔，其基础采用钻孔摩擦桩，结构体系采用支座体系。主桥全宽40m，梁高2．7m，小角度斜跨繁忙运输的电气化铁路线，设双向2．0％横坡、双向2．5％纵坡。桥塔上横梁外挂椭圆形装饰罩，呈拱形门造型。针对该桥实际建桥条件，进行了桥型（支座体系混合式结合梁斜拉桥）、结构（PBL剪力键与剪力钉复合型钢－混结合段）、施工方法（完全依靠汽车吊安装斜拉桥主跨主梁及在结合梁斜拉桥中进行限时合龙）等方面的技术创新。
山東濟寧如意洸府河大橋主橋採用（60＋80＋320＋80＋60） m支座體繫混閤式結閤樑斜拉橋。該橋邊跨採用混凝土邊主樑，中跨採用鋼小邊箱結閤樑，橋塔採用 H形混凝土塔，其基礎採用鑽孔摩抆樁，結構體繫採用支座體繫。主橋全寬40m，樑高2．7m，小角度斜跨繁忙運輸的電氣化鐵路線，設雙嚮2．0％橫坡、雙嚮2．5％縱坡。橋塔上橫樑外掛橢圓形裝飾罩，呈拱形門造型。針對該橋實際建橋條件，進行瞭橋型（支座體繫混閤式結閤樑斜拉橋）、結構（PBL剪力鍵與剪力釘複閤型鋼－混結閤段）、施工方法（完全依靠汽車弔安裝斜拉橋主跨主樑及在結閤樑斜拉橋中進行限時閤龍）等方麵的技術創新。

The main bridge of the Ruyi Guangfu River Bridge in Ji′ning ,Shandong is a hybrid and composite girder cable‐stayed bridge of bearing system type with span arrangement (60+80+320+80+60) m .The side spans of the bridge are of the edge concrete main girders while the cen‐tral span is of the edge steel box composite main girder .T he pylons are the H‐shape concrete py‐lons supported on the foundations of frictional bored piles and the structural system of the bridge is characteristic of the bearing system .The total deck width of the main bridge is 40 m ,the depth of the main girder is 2 .7 m and the bridge obliquely spans the existing busy electrified railways at small angle .The deck of the bridge is provided with 2 .0% dual transverse gradients and 2 .5% du‐al longitudinal gradients .At the upper cross beam of each pylon ,the elliptical decorative cover is installed so that the effect of arch portal configuration of the pylon can be created .In the light of the actual construction conditions of the bridge ,several aspects of the bridge type (the hybrid and composite girder cable‐stayed bridge of bearing system type) ,structure (the steel and concrete joint section using the PBL shear connectors and shear studs) and construction methods (the main girder of the central span of the cable‐stayed bridge to be installed completely by truck cranes and the composite girder cable‐stayed bridge to be closed in limited time) have been technically innova‐ted in the design .
