设计计算书

摘要： 本设计上部结构为钢筋混凝土简支梁桥，标准跨径为14米×3，桥面净空：净—8+2×1.0米，采用重力式桥墩和桥台。桥梁全长为42m，桥面总宽10m，桥面纵坡为0.3%，桥梁中心处桥面设计高程2.00米，横坡为1.5%；桥垮轴线为直线，设计荷载标准为：公路-Ⅱ级，人群荷载3 kN/m。本文主要阐述了该桥设计和计算过程，首先对主桥进行总体结构设计，然后对上部结构进行内力、配筋计算，再进行强度，应力及变形验算，最后进行下部结构设计和结构验算。同时，也给出了各部分内容相关的表格与图纸。通过这次设计不但了解设计桥梁的各个步骤，而且也能熟练的运用AUTOCAD进行制图。

ABSTRACT： The design for the upper structure of reinforced concrete beam bridge, standard span for 14 meters x 3, bridge deck headroom: net - 8 + 2 x 1.0 meters, adopt the piers and gravity type abutment. Bridge deck 42m, stretches for total wide ZongPo 0.3%, 10m bridge deck, deck design elevation 2.00 at the center of the slope for rice, 1.5%; Bridge collapse, design load for linear axis for: highway - Ⅱ standard, the crowd load level 3 kN/m. This paper mainly expounds the bridge design and calculation process, first makes an overall structure design of bridge, then to the upper structure force, reinforcement calculation, again, stress and deformation strength, then check the structure design and structure checking. At the same time, also gives the relevant sections of the form and drawings. This design not only understand each step of designing the bridge, but also can skilled use AUTOCAD for drawing.
Keywords: cast-in-situ concrete simply-supported t-shaped bridge abutment gravity type abutment gravity type structure design checking intensity
