高低应变检测可实现对桩体缺陷位置与完整性的检修,在港口工程桩中一般都需要对桩体进行缺陷性检测。以某码头为例,详细阐述了高低应变检测的原理,并结合工程实践进行检验。实验结果与实际较为吻合,对于该方法的推广应用具有一定的可借鉴性。 High and low strain detection can be achieved on the position and integrity of the pile repair, pile engineering in the port usually require defect detection. Taking a certain dock as an example, the principles of high and low strain detection are elaborated in detail, and combined with engineering practice to test. The experimental results are in good agreement with the actual ones, which is of certain reference to the popularization and application of this method.
