摘要
从超声检测的基本原理出发,详细评述了混凝土声学参数与混凝土质量的关系,通过与低应变法比较,说明对铁路工程中出现的大直径超长桩超声波检测有更高的可靠性,最后结合工程实例,对该方法检测基桩桩身完整性进行了分析验证。
In this paper, the fundamental theory of erosshole sonic logging is summarized, and the relations between acoustic parameters and the concrete quality are introduced. Compared with low strain wave-reflecting method, cross-hole sonic logging have higher reliability for bored cast in-situ pile of railway, especially for large-diameter bored pile. Combined with example, effectiveness of this method has been analyzed and verified.
