Use of Piezocone in Site Investigation for the Canal ťDunav-SavaŤ

Extensive geotechnical and geological investigations were undertaken for the construction of the Danube - Sava canal in eastern Croatia. The route of this 60-kilometer long canal was investigated by combining traditional procedure involving drilling and sample testing with modern penetration techniques as used in soil testing. The investigation was made by cone penetration (CPT) with pore pressure measurement (piezocone) and by Marchetti dilatometer testing. This approach has proven to be quite rational. Stiff clays, being the most frequently encountered material, were additionally investigated at three test sites where correlation was established between parameters for penetration testing and those for borehole and laboratory testing. Based on extensive investigations, appropriate piezocone testing techniques are proposed, including the method for analyzing results from such testing for the design of the entire route.
