Geotechnical Site Characterization on a Cliff for a Dam Construction - Case Study
Background There are many cracks, joints, fractures and karstic spaces on the measurement surface of Limestone. Purpose The main subject of this study is for searching karstic features and voids within the body of local limestone for dam construction. Process The determination of resistivity was performed by geoelectric exploration method with total 28 electrodes at 6m electrode spacing by our client belirti. These 28 electrodes are mounted on the drilled holes on the cliff by using bentonite solutions....
Vertical Electrical Sounding for Geotechnical Site Characterization - Case Study
Background The site borehole information demonstrates that the sediments are sitting on the top of Ignimbrite and there is also fractured Ignimbrite weathered with the content of clay is located at the bottom. Purpose The study was made to determine the sedimentary thicknesses as well as to obtain the contact between high resistivity values associated to Ignimbrite and low resistivity values associated with Ignimbrite fractured and weathered with the content of clays. Process The determination of resistivity...
Use and application of Piezocone Penetration testing in Presumpscot Formation
Abstract: This paper examines the advantages and limitations of CPTu and SCPTu as an exploration method for geotechnical engineering of Presumpscot Formation. Discussion will include typical results of CPTu and SCPTu data for Presumpscot Formation, application and use for settlement prediction, bearing capacity analysis, slope stability evaluation, and seismic design considerations. Intent is to provide an overview of the Use and Application of Piezocone Penetration Testing for the Presumpscot Formation in...
