一、前言随着国民经济的迅速发展,大量的基本建设工程在全国各地普遍兴起,在建设过程中不断提出很多岩土力学问题,其中最突出的问题之一就是桩基基础问题。目前各种类型的桩包括打入桩及钻孔灌注桩正在城市高层建筑及其他工程建设中大量被采用,随之而来的桩的质量检测及桩的承载力问题已引起广泛重视,特别是桩的质量检测问题更为引人注意。目前所采用的检测方法其精度及可靠性究竟如何,是人们非常关心的问题。目前声波法是广泛被采用的
I. INTRODUCTION With the rapid development of the national economy, a large number of capital construction projects have risen throughout the country. Many problems in geotechnical mechanics have been raised during the construction process. One of the most prominent problems is the foundation of piles. At present, various types of piles, including driven piles and cast-in-place piles, are being widely used in urban high-rise buildings and other engineering constructions. The quality inspection of piles and bearing capacity of piles have attracted widespread attention, especially The quality inspection problem of piles is even more noticeable. The exactness and reliability of the current detection methods are of great concern to people. The current sonic method is widely used
