1、摘要南骨干航道網整治工程”的組成部分，配合珥陵鎮市鎮道路改建工程進行建設。道路等級為城市主干路級；通航要求為級航道。本橋址的橋型方案設計主要考慮通航的要求。根據專業知識和查閱參考資梁橋作為推薦設計方案并對此方案進行了詳細的設計。截面，梁高 2.5 ，翼緣寬 19m，底板寬 12 ，腹板厚 0.35 ，主跨跨徑 50 ，混凝土采用 C50，預應力鋼束采用后張法張拉。力，根據結果設計出行車道板所需的鋼筋數量。在計算主梁恒載和活載內力時，進行內力組合，繪出全橋不同橫截面的內力圖。算。進行下部結構計算時：先根據計算出的上部結構內力的大小選擇支座的類驗算以及地基承載力驗算。里所學的知識系統的串聯了起來，

2、運用所學的知識解決了現實生活中的實際問提高。關鍵詞:連續梁、內力、截面、預應力、影響線、樁基礎IABSTRACTThe large bridge of East Red locates the Ling er town of Dan yang city in Jiangsu Province, surmounts the Dan gold canal. It is the Jiang su Province transportdepartment of the southern of Jiang su backbone route net renovates the project theco

The rank of path is the city host II level; the request of open tonavigation is V level of routes.The design of bridge site major consideration navigable clearancerequirements .Then according to the speci

4、alized knowledge and the consult reference,it has formulated three plans: The prestressed concrete continuous bridge; thepre-stressed consecution bridge and the center receive type arched bridge. Throughthe plan comparison, choosing the prestressed concrete continuous bridge as therecommendation des

5、ign proposal and have carried on the further design regarding.The prestressed continuous beam bridge includes the superstructure、thesubstructure、the bearing and the accessory. The main beam is box beam and 2.5meters in height, 19 meters in tope width and 12 meters in bottle width. The web is0.35 met

6、ers in width and detailed scales can get from the paper. The main beamcomputed span is 50 meters. The concrete mark is C50. The Construction method ofhigh tensile wire stranded steel is post-tensioning methods.When superstructure computation, first of all, according to the category of roadsand the v

7、ehicles Loa, the king post upper limb board the endogen force has beencalculated, the design goes on a journey the steel bar quantity which the traffic laneboard needs. When computation king post permanent load and variable load endogenforce, first of all I unit the king post division, then calculat

Increase in endogenforce influence on-line calculates the live load endogen force and carries on theendogen force combination, d

9、raws the entire bridge different lateral sectioning to tryhard. According to the above computed result, the prestressed reinforcement of theentire bridge has been arrangement. The computation loss of prestressed and thepre-stressed cause the inferiorendogenic force,the second endogen force has beenc

The foundation uses the drill hole to pour into the pile and

11、thedefinite detail size. Finally, having carried on the substructure stability as well as theground supporting capacity.In this short more than three months graduation project time, I learn a lot ofknowledge. First I utilize the knowledge system which I studied at university in fouryears, then I used the knowledge to solve the actual problem in real life; Next Ilearned to design in the project according to the standard request on t
