1、 不等跨简支板梁桥 摘 要 该桥为苏州某开发区主要干道上的一座桥梁，桥梁跨越河塘，无通航要求。该桥运用所学的理论知识及结合毕业实习的现场实际经验，通过计算及运用计算机应用软件，采用计算机 及手绘 出图。 该工程钢筋混凝土结构的结合形成及各种原材料计算使用对本人有很大的启发，完成一座桥梁的设计必需先进行调查研究，了解设计深度，对不同设计方案的比较，采用可行的经济合理的方案，考虑各种荷载，得出该桥梁的结构可靠度，按照国家设计及施工规范、强制性条文的要求，利用所学知识，在指导教师的 指导 下，根据不同的结构，选择结 构计算单元，进行荷载计算、竖向荷载作用下内力计算、水平荷载作用下的内力和弯矩计算、截
2、面设计、主梁设计、基础设计（采用钻孔桩基础计算配筋），确定截面的配筋还应满足构造要求。施工图中 ,结构及构件尺寸的标注要齐全 ,受力钢筋、箍筋及构造钢筋的编号清楚、正确。受力钢筋的锚固、连接及截断位置清楚正确。通过本次的毕业设计，使我对桥梁工程的形成及起步初始阶段怎样利用所学的知识进行一个综合认识，为今后涉或进入该行业打好良好的基础。 关键词 桥梁， 钢筋混凝土结构 ， 内力 ， 计算配筋 。 Abstract This bridges for Suzhou some development zone main yang or male principle on bridge, bridge
