| 摘 要： | 格构梁作为一种新型的边坡防护体系,目前在工程实践中已广泛应用。然而工程设计中往往将格构梁拆分为单片梁计算,忽略了格构梁作为整体框架的特点,且设计主要采用手工计算和手工绘图,设计质量和设计速度都难以令人满意。基于以上考虑,利用十字交叉基础设计方法,对纵横梁的荷载分配情况进行讨论,采用Winkler弹性地基梁理论对格构梁的内力进行分析。在此基础上,将格构梁内力计算、配筋计算及施工图绘制集于一体,构建格构梁设计计算系统流程图,利用可视化程序设计语言Visual Basic结合CAD二次开发技术,开发相应的设计计算程序,实现了格构梁设计的智能化和一体化。

| Abstract: | As a new slope protection system, Lattice girder has been widely used in the current engineering practice, but presently lattice girder calculation will be split into single beam in the engineering design, with using the manual calculation and the hand drawing, overlooking the characteristics as a whole framework, whose design quality and design speed are not satis- factory. Based on the considerations above, the cross-based design method is used to solve the problem, which discusses the load distribution on vertical and horizontal girder, and the internal force of lattice beam is computed by Winkler elastic founda- tion beam theory. On this basis, internal force calculation, reinforcement calculation and construction drawings are set to be in- tegrated, establishing the flowchart of design computing system on lattice girder, then the design calculation procedures is de- veloped by visual programming language visual basic with CAD secondary development, and the Intelligent and integration on lattice girder design is realized. |
