摘要
针对架空送电线路基础设计技术规定新旧规范中"剪切法"计算模型的差异化导致掏挖基础结构设计尺寸大小不一的问题,从计算模型与各线路基础设计软件应用的角度,讨论了采用"剪切法"不同计算模型对上拔极限承载力的影响,最后通过掏挖基础在各设计软件中的计算结果比对得到:以新规DL/T5219—2014"剪切法"计算模型为核心的D-software设计结果可靠度较高、经济性较好。
The difference of the calculation model of Shear Method specified in both original and revised specification for foundation design of the overhead transmission line results in different design size of the excavated foundation structure. In terms of calculation model and application of the foundation design software,influences on the ultimate uplift bearing capacity by the different calculation models of the Shear Method are studied in the paper. Through comparison of the calculations of the excavated foundation in various design software,it demonstrates that the design by D- software with the calculation model of the Shear Method specified in the revised specification DL / T5219- 2014 is high in reliability and better in economy.
