抗拔力检测是检验锚固工程质量是否达标的重要手段,目前规范主要从检测的最终荷载和位移两方面进行要求,主要强调的结果控制,但在实际检测过程中,在各级检测荷载作用下,锚固工程亦可能出现异常情况,尤其是检测过程中出现的位移量异常伸长,没有相关条文可参考;从材料力学的基本原理出发,详细计算锚索(杆)在各级荷载作用下的位移和荷载值,通过预先计算,在现场检测中可对比理论值与实测值,实现锚索(杆)检测的过程控制;并通过工程实例介绍其在实际工程中的应用。
The anti-pullout test is an important means to check whether the quality of the anchoring project is up to standard. At present, the specification is mainly from the ultimate load and displacement detection requirements, the main emphasis of the results of the control, but in the actual test process, , The anchoring project may also have abnormal conditions, especially the abnormal elongation of the displacement occurred in the testing process. There is no relevant provisions for reference. Based on the basic mechanics of materials mechanics, the influence of load at all levels Displacement and load value. By pre-calculation, the theoretical value and measured value can be compared in the on-site inspection to realize the process control of the detection of the anchor rod (rod). The application of this method in the actual project is introduced through the engineering example.
