Abstract [en]

Soil-rock total sounding is a further development of soil rock sounding, a MWD sounding method widely used in Sweden, where a static/rotary procedure has been added. Soil-rock total sounding was developed to satisfy the need for a more effective and accurate alternative to the more traditional sounding methods such as Swedish weight sounding and dynamic probing. The method has proven valuable for example when investigating glacial deposits where layers of coarse material frequently occurs which practically limits more precise (and sensitive) methods as CPTu. As a part of the development of soil-rock total sounding, a study has been carried out to investigate whether a correlation can be found between the static/rotary procedure of soil-rock total sounding and the tip resistance of the piezocone test (CPTu). Systematic tests were performed in two geologically different and well defined glacial deposits of sandy soils in Sweden. The result indicated that, at the tested geological formations, an empirical relation can be found between the measured tip resistance of the CPTu and the calculated tip resistance from the static/rotary part of soilrock total sounding. The results also indicated a general relation between the normalized net tip resistance of the CPTu and the normalized net tip resistance of the static / rotary part of soil-rock total sounding in sand.
