长母礼中桥预应力混凝土简支空心板桥设计 ? 摘要 ??? T河桥的设计包括计算部分和图纸绘制。计算部分分为方案比选、上部结构 的计算、下部结构的计算和部分施工组织设计。绘制的图纸有方案比选图、上部结构的构造图、下部结构的构造图和桥梁总体布置图。? ????T河桥总长140m，采用7跨标准跨径20m的预应力空心板，设计荷载为公路Ⅰ级，结构形式为桥面连续的装配式预应力简支空心板。本桥全线采用双向四车道高速公路标准，按分离式进行横断面布置，对其半幅进行了设计。半幅宽度11.25m，由2块边板和6块中板组成，中板宽1.25m，边板宽1.88m。下部结构选用了双柱式桥墩和刚性扩大基础。? ? ???关键词：预应力空心板，双柱式桥墩，施工组织 abricated?simply?supported?prestressed?concrete?slab?bridge ABSTRACT ? ??The?design?of?the?bridge?crossing?T?River?includes?computation?and?drawings.?
