| 摘 要： | 在乐昌至广州高速公路岩溶地区施工中,采用拱型结构跨越大型溶洞的方式处理桥基稳定性受到的影响,并研发了相应的软件评价系统。该系统采用面向对象的可视化编程语言VC++,在VS2005开发平台上运行。利用该系统中的拱型设计模块,针对不同的拱型组合(铰支座个数+拱轴线+荷载组合),可以对3种梁型结构和35种拱型结构的内力进行计算。本文介绍了该软件系统的结构流程、基本功能,并以杨溪河大桥为例,按照"3铰拱+抛物线+5个力"的拱型介绍了该系统的应用。

| Abstract: | According to the karst study in Lechang to Guangzhou Highway project,this paper proposed the arch type crossing method in order to deal with the potential threat to bridge foundation and tunnel caused by the large cave,and developed the corresponding software system,which is exploited on VS2005 development platform by using visual object-oriented programming language VC+ +.Depending on the arch type design module and different arch types(twist bearing amount +arch axis +load),this paper completed internal forces calculation of 3 kinds of girder structure and 35 kinds of arch structure,described the structure process and basic functions of the software,and presented the application of system according to the arch type of "three twist arches + parabola + five forces" by taking the Yangxi river bridge as an example. |
