跨东平水道特大桥为独塔双索面钢混混合梁斜拉桥，跨径组成为(35.0+260.0+51.5+66.0+62.5 ) m。钢主梁采用分离式流线形扁平钢箱梁，正交异性钢桥面板。对钢箱梁剪力滞，桥面系二、三体系应力，钢箱梁扭转等问题进行研究，确保结构受力安全可靠。同时，通过数值分析验证了设计的可靠性。此设计符合技术先进、安全可靠、经济合理等设计原则，其构造形式及分析方法可供类似结构借鉴。
跨東平水道特大橋為獨塔雙索麵鋼混混閤樑斜拉橋，跨徑組成為(35.0+260.0+51.5+66.0+62.5 ) m。鋼主樑採用分離式流線形扁平鋼箱樑，正交異性鋼橋麵闆。對鋼箱樑剪力滯，橋麵繫二、三體繫應力，鋼箱樑扭轉等問題進行研究，確保結構受力安全可靠。同時，通過數值分析驗證瞭設計的可靠性。此設計符閤技術先進、安全可靠、經濟閤理等設計原則，其構造形式及分析方法可供類似結構藉鑒。
과동평수도특대교위독탑쌍색면강혼혼합량사랍교，과경조성위(35.0+260.0+51.5+66.0+62.5 ) m。강주량채용분리식류선형편평강상량，정교이성강교면판。대강상량전력체，교면계이、삼체계응력，강상량뉴전등문제진행연구，학보결구수력안전가고。동시，통과수치분석험증료설계적가고성。차설계부합기술선진、안전가고、경제합리등설계원칙，기구조형식급분석방법가공유사결구차감。
Dongping Waterway Bridge is a single-tower double-sided cable stayed bridge with spans of 35. 0+260. 0+51. 5+66. 0+62. 5m. The steel girder is of separated streamline steel box beam with orthotropic steel bridge deck. Such issues as shear lags, the second system stress, the third second system stress and turn-round related to the box girder are discussed to guarantee the security and reliability of the structure. Meanwhile, numerical method is used to analyze and certify the reliability the design, which is proved to conform to the design requirements for technological advantages, safety, reliability and economic reasonability. It is concluded that structural form and analytical method may serve as references for similar projects.
