摘要
本文在已有成果资料的基础上，为组合拱式管桥的设计建立了常规设计表达式，并研制出组合拱式管桥计算机模拟设计的程序软件ＣＡＰＢＤ。该软件具有以下计算功能：（１）计算组合管拱的几何特征参数；（２）计算组合管拱自重和组合拱式管桥的竖向荷载及其材料费用；（３）分析和计算各种载荷作用下组合拱式管桥的内力；（１）组合拱式管桥各控制截面强度校核、稳定性验算以及拱支墩稳定性验算和地基承载力强度校核。使用结果表明，该软件运算迅速、操作简便、结果准确可靠，对减轻设计人员的劳动强度具有一定的工程实用价值。
In order to improve the design level of Combined-Arch Pipe Bridge (CAPB), this thesis established more detail expression formula of conventional design on the basis of the existing achivements on CAPB,and developed a computer simulating design software, named CAPBD. The software has the following calculating functions: ①calculating the parameters of geometric characteristic on combined pipe-arch; ②calculating the self weight of combined pipe-arch, vertical load and material costS of CAPB; ③analyzing and calculating the internal force of CAPB under various kinds of load; ④strength and stability checking at all control sections of CAPB, stability verification of buttress and checking of ground bearing capability. The result shows that the software is rapid in calculation. convenient in operation,accurate and tenable. It has practical value in engineering for relieving the labour strength of designer.
