STUDI REKAHAN PADA TEROWONGAN KERETA API DENGAN METODE GROUND PENETRATING RADAR (GPR) (STUDI KASUS DI DAERAH SASAKSAAT) PADALARANG JAWA BARAT

Abstract

Ground Penetrating radar (GPR) is a geophysical method that uses electromagnetic wave propogation and has a high resolution towards dielectric contrast in rocks. In this paper, the method is radar reflection profiling and data prosessing by using software Reflex W Test Version. In situ measurement of electromagnetic was carried out by georadar method using Ramac GPR at frequency of 200 MHz in side of tunnel. The result of the measurement indicate there are many joint in the concrete of tunnel wall it trade
mark carbonate calsite in the stone.
