Line Load Combination Calculation Software for Transmission Tower Based on European-American Standards

摘要:

在输电杆塔结构导地线荷载的计算上，中美欧标准存在一定的相似性，但也存在较大的差异，导致基于中国标准的设计软件无法适用于欧美标准，降低了杆塔设计效率。由于不同地区具体要求不同，目前行业内尚无可用的基于欧美标准的荷载组合通用软件。首先，对中美欧输电杆塔标准荷载组合规定进行了对比研究，总结了中美欧荷载组合的相同点和差异点；然后，在借鉴国内类似软件开发经验的基础上，基于VB.NET语言和欧美标准研发了一套杆塔导地线荷载组合程序，详细介绍了程序原理和结构并对关键技术进行了重点介绍；最后，举例演示了程序的具体应用，为国外工程设计提供参考。

Abstract:

For line load calculation of transmission tower structure, there are some similarities between European American standards and Chinese standards, but there are also great differences between them. As a result, the design software based on Chinese standards is not applicable for foreign projects, which reduces the design efficiency. For far, there is no general software for load combination based on European American standards available in electric power industry. Firstly, the similarities and differences are analyzed and discussed, and the research results of the related software are referred. And then, based on these, an efficient visual operating program system aimed to realize line load combination calculation of transmission tower based on European-American standards is developed by VB.NET program. The principle and the structure of the proposed program are introduced in detail as well as the key technology of the program. At last, an example is demonstrated, hoping to provide some help for foreign engineering design.
