摘要
[目的]铁塔基础配置结果直接影响基础方案的准确合理性,需要解决铁塔高低腿人工配置速度慢、精度低的问题。[方法]通过常规配置过程分析,及配置结果对比分析,提出人工配置过程中的问题。人工配置时精度较低,特别对于地形较陡或大坡比铁塔的情况人工配置结果可能影响基础安全或基础设计基面偏于保守。通过常规人工配置过程问题分析,提出逆向配置方法并研发三维配置程序。[结果]采用逆向配置法配置同一基塔,结果表明逆向配置法结果精确,可快速准确计算各参数同时准确计算实际基础露高。[结论]逆向配置方法精度及效率远优于人工方法配置,配置结果直观准确,推荐工程中采用此法配置铁塔高低腿。
[Introduction]The result of tower foundation configuration directly affects the accuracy and rationality of the foundation scheme.The problem of slow manual configuration speed and low accuracy of tower height-low leg need to be solved.[Method]This paper analyzed the configuration process and configuration result,and then this paper put forward the problems in the manual configuration process.The accuracy of manual configuration was low,especially for towers with steep terrain or large slope ratio.The manual configuration results may affected the safety of foundation or caused the foundation design parmeters to be conservative.Through the problem analysis of the conventional configuration process,a reverse configuration method and a 3D configuration program were put forward in this paper.[Result]The reverse configuration method is used to configure the same tower,and the result of the reverse configuration method is accurate,which can quickly and accurately calculate the various parameters and accurately calculate the actual exposed height.[Conclusion]The accuracy and efficiency of reverse configuration method are better than that of manual configuration,and the configuration results are intuitive and accurate.It is recommended to use the method to configure the high-low leg in engineering.
