ARHITECTURĂ THE IMPACT OF THE COMPACTION PROCESS ON THE VARIATION OF SOIL HYDROPHYSICAL PROPERTIES FROM BREAZU AND DANCU AREAS BY VIOREL FILER * , FLORIAN STĂTESCU and ADRIANA UNGURAŞU (STAN) “Gheorghe Asachi” Technical University of Iaşi, Faculty of Hydrotechnics, Geodesy and Environmental Engineering Received: May 11, 2016 Accepted for publication: June 15, 2016 Abstract. The present study wants to highlight the influence it has compacting process on the variation of hydrophysical.properties of three types of soil In solving this unfavorable soil phenomenon this paper tries to noting the main effects exerted by the compaction process on the hydrophysical.properties distribution in time and space by applying laboratory methods for determining the physical and hydraulic properties of soils in Breazu and Dancu areas. Principal physical characteristics were determined: soil density, soil bulk density, texture and soil porosity. Hydraulic properties analyzed in order to mark the variation of water regime were: hydraulic conductivity (saturated and unsaturated) and soil suction. All these basic attributes of soil were determined in laboratory methods of applying wish traced internationally. Keywords: compacting; physical properties and hydraulic properties. * Corresponding author: e-mail: stef_vio2000 @yahoo.com
