摘　　要：针对外场载荷测试试验具有场地不固定且基础设施不完善的特点,提出了一种二力杆件结构载荷测试地面标定方法,以应对外场条件下不同类型二力杆件结构载荷测试地面标定试验。设计了二力杆件结构载荷测试地面标定试验装置,利用有限元软件对试验装置进行分析计算,得到二力杆件所受载荷,理论计算结果与有限元仿真结果相吻合,这为外场条件下二力杆件结构载荷测试提供了一种工程测试途径。According to the fact that the external field test has the characteristics of unfixed site and imperfect infrastructure,a ground calibration method for the load test of two-force bar structure is proposed in the paper to deal with the ground calibration of load test of different types of two-force bar under the external field condition.A ground calibration testing device for the load test of two-force bar structure is designed.The testing device is analyzed and calculated by finite element software,and the load applied on two-force bar is obtained.The theoretical calculation results are consistent with the finite element simulation results.It provides an engineering test way for the load test of two-force bar under the external field condition.
