Abstract

The complex hydrotechnical works achieved upon the lower basin of the Olt river, within the southern part of Romania, imposed the building of several large reservoirs situated within the geo-morphological unit of the above named river flood plane. During the last years, due to the recent earthquakes that affected Romania, the macro-earthquake zoning of the country was changed. In these conditions, the problem of studying the stability of dikes foundation ground from the liquefaction point of view has raised. The paper presents the survey done in site and laboratory tests performed in order to determine most accurately, the natural ground geotechnical and dynamic parameters as well as an original method in order to estimate the ground liquefaction potential. Finally, the general stability analyses of the assembled dike-foundation ground is presented in pseudo-static hypothesis with taking into account the geotechnical parameters expected in dynamic conditions.

Liquefaction Potential of the Hydrotechnical Dikes Foundation Ground

New York, New York

The complex hydrotechnical works achieved upon the lower basin of the Olt river, within the southern part of Romania, imposed the building of several large reservoirs situated within the geo-morphological unit of the above named river flood plane. During the last years, due to the recent earthquakes that affected Romania, the macro-earthquake zoning of the country was changed. In these conditions, the problem of studying the stability of dikes foundation ground from the liquefaction point of view has raised. The paper presents the survey done in site and laboratory tests performed in order to determine most accurately, the natural ground geotechnical and dynamic parameters as well as an original method in order to estimate the ground liquefaction potential. Finally, the general stability analyses of the assembled dike-foundation ground is presented in pseudo-static hypothesis with taking into account the geotechnical parameters expected in dynamic conditions.
