| 摘 要： | 在土木基础工程研究和监测中常常使用应变片测量构件的应变,计算其应力。但应变片受到土压力等正压力的作用对应变的准确测量将产生影响。采用试验方法研究正压力对应变片应变测量的影响。研究发现,在待测应变较小时,正压力对应变测量值产生的影响较大,在10%左右;当待测应变较大时,正压力对应变测量值产生的影响在5%左右。

| Abstract: | Strain gauge is often used to study and monitor the strain of the component in the foundation.But the positive pressure applied to the strain gauge will influence the strain measuring.The experiments were done to study the influence.The study indicated that the positive pressure would influence the measuring of strain.As the strain to be measured was small the influence was bigger,about 10%.As the strain to be measured was bigger the influence was about 5%. |
