Summary

Engaging in the subject of geophysical and geotechnical research, in which the results are defined from the data of the ground, has manifested a rapid development in geotechnical and environmental geophysics. This postgraduate dissertation is looking at the conducting of measurements, their processing and their interpretation in geophysical and geotechnical level in the site of Kissamos in the regional unit of Chania. The purpose of this research is to check the suitability of the site of interest for the installation of a Hybrid Plant in the “Stavros-Kisos” area. The 1.95MW power Hybrid Plant in the “Stavros” site will consist of two wind turbines while the 5MW power Hybrid plant in the “Kisos” site will consist of four wind turbines of the Gamesa G114 type. Also, there will be an Inspection Center and Storage System building in each of the two sites.The work activities of the geophysical exploration were conducted using the method of electrical and seismic tomography and also with the method of the electrical exploration. The work activities of the geotechnical research were conducted using laboratory tests with the method of unconfined compression and with the triaxial tests of constrained high and low voltage, after having collected a suitable sample from the site of interest. The data arose after conducting relevant work activities in open ground for the geophysical research and laboratory tests for the geotechnical research, for both of which it was regarded necessary and essential to be conducted in the site of the wind turbines, in the Inspection Center and in the Storage System so as to ensure the safe installation of the Hybrid Plant. The maximum depth of the exploration was defined up to 8m. Regarding the geophysical data, they were processed with the use of suitable software programs as well as with inverse methods. In particular, as for the electrical tomography, the following software programs were used: the Res2Dinv software program was used for the imaging of the geoelectrical sectors for all installation sites, the Res3dinv software program was used for the imaging of the three-dimensional sectors of the first wind turbine in the site of “Kisos” (west side) and the Prosys software program was used for the inclusion of altitudes in each study line. The inverse method which was used is the Smoothness constraint Inversion. The process of the seismic data was conducted using the following software programs: the PickWIn and Poltfera software programs were used for the seismic refraction and the multi-channel surface wave analysis method (AMSW) was used for the surface waves .Also, the KRISIS software program in MATLAB environment was used to process the data of the MASW method.
