Fracture and Cavity Detection and Mapping in construction foundations case study-2
Area of Implementation: Rethymno, Crete, Hellas
System Used : SIR-10A (GSSI) w Antenna 300MHz (GSSI)
Scope : To detect and map fractures and cavities in bedrock at a water tank construction site
Method of investigation: Profile Grid: Profiles A to D and 1 to 10. Α1, Α2, Α3, A4 & A5: drill holes, profile spacing: 5m.
GPR Data Processing & Software Used : WinRAD 3.1 (GSSI) and RADAN V.6: Boxcar Stacking, LowPass FIR, Migration, Hilbert
Profile Interpretation : Fracture and weathered Rock mass was detected and mapped. Measures related to pillar foundation were proposed.
3D representation: WinRad 3.1
