ANALYSIS ON THE COMPREHENSIVE APPLICATION OF LOW STRAIN REFLECTION WAVE METHOD COMBINED WITH ACOUSTIC TRANSMISSION METHOD OR DRILLING CORE METHOD IN FOUNDATION PILE DETECTION

Abstract

The low-strain reflected wave method has the characteristics of convenience, rapidity and low cost to detect the integrity of foundation piles, and it occupies a certain proportion in the non-destructive testing of bridge pile foundations. This paper will introduce the principle of the low-strain reflected wave method and explain the comprehensive application analysis of the low-strain reflected wave method combined with the acoustic wave transmission method or the core drilling method through three engineering examples.
