In situ soil-investigation methods for soil mechanics and foundation engineering in delta regions

Abstract

There now exists a great variety of investigation methods and measurements which can be applied in the field to derive appropriate and reliable information from the soil strata with respect to their behaviour as a foundation for civil engineering constructions. The basic principles of in situ measurements in deltaic areas and especially in The Netherlands are given and some of the most interesting and recently developed devices are described. Although every apparatus causes a certain disturbance of the soil strata, in practice the measuring results often appear to be sufficient and serviceable.
