STUDY OF A SOIL ASSESSMENT METHOD BASED ON SOUNDS GENERATED BY ROTARY SOUNDING

Abstract

This report considers the practicality of a soil assessment technique based on sounds generated during rotary sounding by applying the technology used in a shield tunneling. Laboratory experiment, model ground experiment and numerical analysis have been executed. The results of them have revealed that it is possible to quantitatively assess the difference in the sounds recorded for different soil types to estimate their grain size distribution.
