표준관입시험 및 시추공 정보를 이용한 국내 전단파속도 예측 = VS Prediction Model Using SPT-N Values and Soil Layers in South Korea

다국어 초록 (Multilingual Abstract)

The national ground survey database (GeoInfo) distributes numerous ground survey data nationwide. Many standard penetration test results exist in this database; however, the number of shear wave velocity (VS) data is small. Hence, to use abundant standard penetration test-N values to predict VS, this study proposed a new empirical N-VS relationship model using GeoInfo data. The proposed N-VS model is a single equation regardless of geological layer types; the layer type only specifies the upper limit of VS. To validate the proposed model, residual analysis was performed using a test dataset that was not used for the model development. Therefore, this study’s proposed model performed better than N-VS models from previous studies. Since the N-VS model in this study was developed using sufficient data from GeoInfo, we expect that it is the most applicable to GeoInfo dataset for VS prediction.
