1、-.摘要随着我国社会的开展与进步和人民的生活水平的日益提高，交通的便利程度和平安性得到了人们的广泛关注，桥梁又是现代交通中不可缺少的组成局部，我国桥梁工程无论在建立规模上，还是在科技水平上，均已跻身世界先进展列。本设计为S17线金昌至永昌高速公路河东庄大桥〔两联4×25m预应力混凝土连续箱梁〕下部构造设计，在设计过程中，参考了诸如桥梁工程、土力学、桥涵水文、材料力学、专业英语等相关书籍和文献，根据?公路桥涵设计手册?系列丛书，依照交通部颁发的有关公路桥涵设计规〔JTG系列〕拟定设计而成。设计中考虑了各种尺寸与材料的选用符合规中对强度、应力、局部承
2、压强度的要求，并且产生在规容许围的变形，使桥梁在正常使用的情况下能够到达平安，稳定和耐久的标准。在可预期偶然荷载下仍能到达根本正常使用的标准。设计时还充分考虑河东庄大桥所处区域的地质和水文条件，既保证符合规要求，同时保证因地制宜并且便于施工和维护，并且兼顾桥梁本身的美观性与社会经济性，既要设计合理，又要起到良好的社会经济效益。关键词：河东庄大桥下部构造桥墩桥台美观性经济性AbstractWiththedevelopmentandprogressofoursocietyandpeople'srisinglivingstandards,transpo
