For this purpose, the Ground Penetrating Radar (GPR), Electrical&lt;br&gt;Resistivity Tomography (ERT), Seismic Refraction Tomography (SRT) and Multichannel Analysis of&lt;br&gt;Surface Waves (MASW) techniques were implemented in the area. The cores of three geotechnical&lt;br&gt;boreholes existing in the area have also been taken into account. The application of the GPR and ERT&lt;br&gt;techniques did not reached a satisfactory investigation depth, however the existence of a possible&lt;br&gt;mechanically degraded zone have been adumbrated at the south part of the excavation area. Through&lt;br&gt;the application of the SRT and MASW techniques, the seismic waves velocities of the investigated&lt;br&gt;lithological formations were calculated and the subsurface structure of the study area was outlined.&lt;br&gt;Additionally, lateral variations in the P-wave seismic velocities, especially in the first investigated&lt;br&gt;seismic layer, provided further evidence for the existence of mechanically unstable zones, which&lt;br&gt;necessitate a more detailed investigation. Finally, from the laboratory determination of the formations’&lt;br&gt;densities and their seismic wave velocities, their elastic moduli and geotechnical parameters have been&lt;br&gt;calculated.&lt;/p&gt;</style></abstract></record></records></xml>
