笔者赴香港时了解到有关桩基无损检测状况。本文着重介绍几种桩基无损检测方法的原理、仪器设备和资料分析解释方法。并结合本人从事桩检工作的实践和体会,对国内外这方面的工作,进行简要的对比和评价。以期与从事地球物理工作的同事们共同努力,不断开拓物探方法的新应用领域。随着大型建筑结构的不断涌现,不同成 When I went to Hong Kong, I learned about the status of nondestructive testing of pile foundations. This article focuses on the principles, instrumentation, and data analysis and interpretation of several non-destructive testing methods for pile foundations. Combined with my own practice and experience in the work of pile inspection, I will briefly compare and evaluate the work in this area at home and abroad. With a view to working with colleagues engaged in geophysical work, we will continue to explore new applications for geophysical exploration methods. With the continuous emergence of large-scale building structures, different
