| 摘 要： | 文中探讨了一种非破坏性的测量技术——电磁传感检测,利用索中放置的电磁传感器,通过测量磁通量的变化来测定索力。这种新型的电磁传感器可用来监测民用建筑中钢索和钢筋中的张力,也可以监测大型铁索桥梁长期稳定情况。磁通量法在国外已用于各种结构的应力测试,获得了较好的效果,在我国也初见成效。

| Abstract: | The article describes a kind of non-destructive measurement technology--electromagnetism sensor technology, using the electromagnetism sensor which is fixed through the tightwire to measure the strength of the hawser. This system can be used to monitor the cable and tightwire in the public building, and also used to monitor the large tightwire bridge. Electromagnetism Method has been utilized for various structures stress tests and made good results abroad, and now it also causing great concern in our country. |
