Application of multi-geophysical approach for detection of cavern

This paper presents application of multi- geophysical approach for detection of a cavern between two lanes of Rijeka - Zagreb highway in Croatia. Applied geophysical methods were ground penetrating radar (GPR) and seismic refraction method. While the ground penetrating radar method gave information of the degree of karstification of rock mass under the highway, seismic refraction gave an estimation of cavern dimensions. Basic principles of both methods are given in paper as well as the results of investigation works which consisted of 21 GPR profiles and one seismic refraction profile. Also, cavern remediation works, which are based on results on investigation works, are presented in paper.
