Abstract
Comparative analysis of the results of geophysical and geological- -engineering methods on the example of Włocławek River-islet investigative testing ground.
A b s t r a c t. The paper present the correlation of geophysical method with geological-engineering data. As an experimental testing ground, a terrain with simple soil conditions was selected, located on the Włocławek River-islet. This is a large alluvial area on the Vistula River, downstream of the Włocławek Dam. In the study, the following geophysical methods were applied: vertical electrical sounding (VES), refraction seismic, ground penetrating radar (GPR) and electrical resistivity tomography (ERT). The evaluation of geological-engineering conditions was executed by using the following methods: drilling, cone penetration test (CPT sounding), measurements of the underground water level and macroscopic and laboratory analyses of soils samples. The results obtained were described and presented in a graphic form.
