简要介绍上海金山铁路改造项目中既有桥利用、加固、改建的原则和门式墩、“歪脖子”墩、槽形梁、下承式钢桁梁等低高度结构的设计.根据金山铁路的技术特点,研究采用了“密布横梁体系钢正交异性板道砟整体桥面”新技术、“MMA + CAP”桥面轻质垫层体系新材料、“简支梁平面转体”和“框架桥无便梁顶进”新工艺,以期为其它既有线改造项目提供有益的借鉴.
簡要介紹上海金山鐵路改造項目中既有橋利用、加固、改建的原則和門式墩、“歪脖子”墩、槽形樑、下承式鋼桁樑等低高度結構的設計.根據金山鐵路的技術特點,研究採用瞭“密佈橫樑體繫鋼正交異性闆道砟整體橋麵”新技術、“MMA + CAP”橋麵輕質墊層體繫新材料、“簡支樑平麵轉體”和“框架橋無便樑頂進”新工藝,以期為其它既有線改造項目提供有益的藉鑒.
간요개소상해금산철로개조항목중기유교이용、가고、개건적원칙화문식돈、“왜발자”돈、조형량、하승식강항량등저고도결구적설계.근거금산철로적기술특점,연구채용료“밀포횡량체계강정교이성판도사정체교면”신기술、“MMA + CAP”교면경질점층체계신재료、“간지량평면전체”화“광가교무편량정진”신공예,이기위기타기유선개조항목제공유익적차감.
@@@@This paper presented the general principle of the existing bridge utilization,strengthening and reconstruction of ShangHai-JinShan district railway,introduced the low height structure design methods of portal pier,eccentric bridge pier,u-shaped beam,and through steel truss bridge,and studied the new technology of whole orthogonal steel ballasted deck with densely covered transverse girders,new light quality underlayment material of bridge deck with MMA + CAP,the swing method of simple supported beam and thrust construction without temporary beam,which could provide a reference for other existing railway line reconstruction projects.
