摘要
本文提出了用基频参数检测混凝土桩基质量的一种新的无损动测法。文中介绍了该法的基本原理。列出了一波动方程,并根据实际的初始条件和边界条件导出了频率方程。根据三种不同的地基刚度导出了纵波速度V_p和基频f_b之间的三种关系式,并列举了应用实例。
This paper proposed a new dynamic non-destructive inspection method for testing concrete pile quality using the fundamental frequency parameter. The basic principles of this method are presented, The one-dimentional wave equation is derived on the basis of actual initial and boundary conditions. According to three different kinds of foundation stiffness, the relationships between V_p and f_b are derived respectively. Some practical examples are also described.
