摘要： 依托沈阳某工程的桩基础工程,用声波透射法对大直径灌注桩桩身完整性进行检测,分析了该工程的检测数据,判定了桩身完整性类别.在此基础上,利用无损检测理论,研究推算了桩身实体结构强度.应用统计分析的方法,建立本次试验的声速与强度之间的回归方程,回归结果与工程实际符合,为确定桩身混凝土强度提供了快速简便的方法.

Abstract: Based on pile detection work of a project in Shenyang, the integrity of large-diameter piles was detected by cross-hole sonic logging to determine the integrity categories of the piles. The structure strength of piles was estimated according to the theory of nondestructive exam. Statistical analysis method was used to establish the regression formulation of sound's speed to strength. The results showed a good agreement with the project fact, and provided a simple and fast method to determine the concrete strength of the pile body.
