摘要
Abstract
The principle for detection of the quality of concrete in foundations piles with the ultrasonic transmission method is discussed from the viewpoint of the characteristics reflected by ultrasonic acoustic parameters and the advantages and deficiencies of various acoustic parameters in assessing the quality of concrete in foundation piles are emphatically analyzed. Based on the case study of a project,it is believed that the integral assessment method incorporating ultrasonic acoustic parameters can quite comprehensively and accurately detect the quality of concrete piles and meet the developing demand of modern engineering works.关键词
