Abstract

PRELIMINARY REMARKS ON THE INTERPRETATION OF DYNAMIC AND STATIC PROBINGS Summary The relative density of non-cohesive soils in situ may be obtained by means of dynamic and static sounding. In Poland dynamic sounding is more commonly used, especially the cone penetrometer (ITB-ZW) and the standard penetration test, whereas described Dutch penetrometer test was performed for the first time. Factors influencing interpretation of the results of both dynamic and static sounding are given. The most important of these include: type of soil, depth of sounding, and soil moisture. The principles of interpretation of the results of two sounding techniques are discussed. The paper presents the results of sounding obtained for alluvial soils from the area of construction of a power plant. The sounding were carried out by means of cone penetrometer (ITB-ZW) and Dutch penetrometer. The analysis of the results was carried out by taking into account the above factors influencing the interpretation. Moreover, the changes in substratum, resulting from the construction of plant foundations and from drainage of waters are discussed.
