摘要，本设计是凌云至百色二级公路上的一座跨百色xxx的一座大桥。充分考虑了与公路线性的结合，参照了现有的标准图。并对桥梁方案的初步定制和方案的必选进行了充分的论述，最终选择了“装配式预应力T型简支梁桥”这一方案；在设计过程中，桥梁上部结构的计算着重分析了桥梁在使用工程中恒载以及活载的作用力，采用整体的体积以及自重系数，荷载集度进行恒载内力的计算。运用“比拟正交异性板法”求出活载横向分布系数，并运用最大荷载法法进行活载的加载。进行了梁的配筋计算，估算了钢绞线的各种预应力损失，并进行预应力阶段和使用阶段主梁截面的强度和变形验算、锚固区局部强度验算和挠度的计算并采用矩形氯丁橡胶支座。下部结构参照标准图采用盖梁、系梁，采用刚性基础的双墩柱，并分别对桥墩和桩基础进行了计算和验算，在此计算过程中运用了桥梁博士V3.0、VB6.0等软件。设计全部设计图纸采用计算机辅助设计绘制，计算机编档、排版，打印出图及论文。关键词：预应力混凝土 简支T梁 盖梁 双柱式桥墩 刚性基础板式橡胶支座 重力式U型桥台 桥梁博士V3.0 VB6.0
The integrated design of Chengbi River Bridge in Baise-- Design of Substructure（Guangxi University College of Civil construction Engineering (transportationcivil engineering direction )2005 Huangping）Abstract :This desigen is a big bridge cross the ChengBi River for asecondary road of LinYun to BaiSe. Fully taken into account the linear combination of highway, Reference existing marked graph,and Bridge program and the initial customization and mandatory programs have been fully discussed, Eventually opted for the "T-fabricated simply supported prestressed girder bridge" of the program; During the design process, bridges the upper part of the calculation will focus on analyzing the structure of a bridge project in the use of dead load and live load forces, as well as the use of the size of the overall weight factor, load carrying out a set of internal force calculation of dead load. The use of "orthotropic plate analogy method" to derive the horizontal distribution of live load factor, and the use of France and France carried out the biggest load of live load to load. Reinforcement to the beam, the estimated range of prestressed steel strand loss, and stage and the use of prestressed girder cross-section of the main stage of strength and deformation checking, checking the strength of local anchorage zone and the calculation of deflection and the use of chlorine rectangular butadiene rubber bearings. The lower part of the structure of the light beam covered the use of standard plans, tie beam, based on the use of rigid double-pillar, and, respectively, on the pier and pile foundation are calculated and checked, in this calculation using the Dr. bridge V3.0 、Visual Basic 6.0 and so on.The design of all the design drawings using computer-aided design drawing, computer archiving, publishing, print out maps and papers.
