摘要


本设计的步骤为:根据设计任务要求,依据现行公路桥梁设计规范,综合考虑桥位的地质、地形条件,经初选后提出了五跨连续梁桥、钢桁腹PC梁+琴拱、预应力混凝土连续梁+琴拱三个比选桥型。按“实用、经济、安全、美观”的桥梁设计原则,比较三个方案的优缺点。比选后把钢桁腹PC梁+琴拱作为主要推荐设计方案,并进行了结构细部尺寸拟定、主梁内力计算、主梁和桥墩配筋设计及控制截面强度、应力验算,活载变形验算等。经分析比较及验算表明该设计计算方法正确,内力分布合理,符合设计任务的要求。

CONSTRUCTION DESIGN FOR LIUZI ISLAND BRIDGE MAIN CHANNEL ON SECOND RING ROAD IN NINGXIANG COUNTY


ABSTRACT


The process of designment:According to the design assignment and the present Highway Bridge Specifications, Take the geological and the landform of the bridge site for further analysis, after preliminary selection, three bridge type schemas are presented, they are Five-span continuous beam bridge, PC girder steel truss belly +Qin arch and Prestressed concrete continuous beams+Qin arch. Comparing their characters comprehensively, PC girder steel truss belly +Qin arch is selected as the main design scheme by the philosophy of bridge design as “Practicability, Economy, Security, Beauty”. Through drawing up of structure’s dimension, internal force calculation of dead and living load, prestressed steel design, hypoforce calculation, assessment of prestressing loss, checking computation and pier of key section intension, stress, living load distortion, The conclusion can be drawn that the design is up to the assignment.


Key word: Program Comparison; Five-span continuous beam bridge; PC girder steel truss belly +Qin arch; Prestressed concrete continuous beams+Qin arch; Structure analysis
