摘要
结合某工程的桩基检测工作实例,在声波透射法对大直径超长桩桩身完整性检测的基础上,对该方法用于检测桩身承载力进行了研究。根据超声法检测混凝土强度的理论,通过对现场声波检测和钻心法的数据进行回归分析,提出该工程测桩的声速-强度公式。实践表明,该方法具有快速、准确、无损、经济可靠的特点,具有一定的现实意义。
Combined with some examples in testing a pile - base project and on the basis of a test of the integrity of the body of the large - diameter ultra long piles in crosshole sonic logging method, a study on the method used in testing the bearing strength of the pile body is made. According to the theory used in measuring the concrete strength in ultrasonic method and through the regression analysis on the data from the in - situ sound - wave test and core drilling method, an equation of sound speed to strength for testing the piles of the project is raised. It has been proved that this method has the characteristics of high - speed, correctness, harmlessness and economic reliability, and so some realistic significance.
