Influence of Drilling Methods on the Results of Standard Penetration Test in Loess–Paleosol Sequence

Abstract: Standard penetration test (SPT) is an important in situ measurement for field investigation of geotechnical and geological engineering. The drilling approaches for implementation of SPT can be classified into dry, wet, and water circulation drillings according to the amount of water used during drilling process. However, the influences of these drilling methods on the SPT results remain unclear, especially when being used in loess–paleosol sequence that is water sensitive. In this study, SPT tests were conduct… Show more

“…Geotechnical and Borehole Data. SPT approach was applied to determine soil stiffness, thickness, and depth of the near-surface materials [37,38]. For this purpose, forty one SPT borehole data were collected from private organizations for the site characterization, correlation of Vs and SPT-N values, and seismic site classification [39,40] (Figure 3).…”
