摘要
建立了锚杆动测问题的有限元模型,并对锚杆中的缺陷进行了数值模拟,获得了位移场的数值解。对该解在时域和频域范围内的讨论表明,锚杆中的缺陷将引起动测曲线一系列的变化,为现场动测曲线的识别提供了依据。
This dissertation has build up finite element model of dynamic detection of the anchor bolt, meanwhile made numerical simulation of flaws in anchor bars and gained the numerical solution of displacement field. The discussion on the solution in time domain and frequency domain has shown that the flaws in the anchor bar will lead to a series of changes of detecting curves. It is useful to identify the detecting curves on a site test for reference.
