Compater Analysis of Statical Characters of the Basket-type Semi-Crossing Pipe Bridges

本文在总结近年来关于组合拱式管桥和提篮半穿式管桥的研究成果的基础上,全面系统地论述了分析提篮半穿式管桥静态特性的各种有效方法。鉴于提篮半穿式管桥静态特性公式的复杂性,笔者为了克服手算可能遇到的诸多麻烦,进而为设计人员提供简便、快速的设计方法,使用BASIC语言编制了这个设计软件。应用该软件在普通微机上即可完成提篮半穿式管桥的几何特性分析、内力计算、强度校核和稳定性验算等大量复杂的计算工作。举例应用表明,该设计软件具有人机对话式交流的灵活性和计算精度高的可靠性。

Based on the summarization of study results in the combined arch pipe bridges and the basket-type semi-crossing pipe bridges achieved in recent years, this paper discusses various effective methods in the static analysis of basket-type semi-crossing pipe bridges. Owing to the complication of many formulas analyzing basket-type semi-crossing pipe bridges, the authors develop this design software with BASIC language, in which the static characteristics of a basket-type semi-crossing pipe bridge can be calculated, in order to overcome some troubles that may be arisen in manual calculation and provide designers with a convenient and fast-speed design method. The analysis of geometrical configuration, calculation of internal forces, examination of strength, checking of stability and other complicated calculations in a basket-type semi-crossing pipe bridge can be done by a common micro-computer with this software. It is shown that by an applied example, this design software possesses the flexibility of communication by interviewing between man and computer as well as the reliability of high precision in calculation.
