| 摘 要： | 应力应变测试是准确掌握结构各部分构件受力状态的重要手段。基于对多种复杂作用力耦合构件的现场荷载试验,通过在同一锚杆上使用多种仪器测试,揭示复杂受力状态下合理的构件应力应变测试方法。研究指出：复杂受力时可采用多面粘贴应变计的方法进行应力应变测试;应变式测试仪器适用短期应力测试;长期观测,建议使用振弦式应力测试仪器。

| Abstract: | Stress-strain test is an important means to grasp the accurate stress state of some elements of the structure.Through the use of multiple instruments on the same anchor test with complex force during the load test in the field,to reveal the appropriate strain and stress test methods for the components with complex force.The study indicated that： we can use strain gauge on the multi-faceted of complex force components to get the stress;strain test instrument applies to short-term stress tests;it is recommended to use vibrating wire stress testing equipment for the long-term observation. |
