摘要
低应变反射波法是近年来应用比较广泛的桩基础检测技术。针对基础施工过程中常见的断桩、缩颈、扩颈、离析等质量问题,简要介绍了低应变反射波法的基本原理。同时结合现场数据采集和室内试验数据分析,对低应变反射波法桩基检测进行了初步探讨,并从工程实践中得到了相应的验证。
Low strain reflected wave method has been a widely used technology of pile foundation detection recently. In connection with common engineering quality problems in the foundation construction progress, such as broken pile, necking, widening from folding and other problems, this paper illustrates the basic principles of low strain reflected waves law briefly. Meanwhile, combining with the filed data collection and the indoor trail data analysis, it investigates preliminarily the pile de- tection with the low strain reflected wave method, and it has got a corresponding verification from engineering practice.
