摘要
本文扼要介绍瞬态激振（敲击）时域频域分析法基桩质量无损检验新技术的基本原理、测试方法以及在工程中的应用，所举实例都经过了钻孔取芯等方法验证。实践证明，瞬态动力法基桩检测技术科学实用、技术可靠、精度高。同时，由于桩土体系的复杂性，动力测桩法涉及的内容又比较广泛，所以该项技术具有广阔的开发前景和需要不断完善的地方。文章最后谈几点粗浅的认识以供探讨。
The paper introduces the basic principles, testing methods and application of engineering upon dynamic pile nondestructive testing. Based on the plenty engineering practices,a series of new, effective and suitable technical measures are summarized and expounded bythe author in this paper. They are valuable for reference.
