Development of in-situ tunnel-ahead detection system using e… During tunnel construction, the unexpected occurrence of anomalies ahead of the tunnel face, such as weak zones, fault zones, and cavities, may cause mechanical failures and ultimately result in casualties. For this reason, various methods to predict the geotechnical ground conditions in advance hav…

Prediction of the hydraulic conductivity of the rock mass us… In countries like South Korea, various studies to construct tunnels and underground structures are performed due to the existence of many mountains and rock-consisting underground space. Therefore lots of attempts have been tried to characterize the rock and the rock mass. However, it is very diffic…

Shear strength estimation of sandy soils using shear wave ve… Typically, shear strength is associated with large strain phenomena, while shear wave propagation is associated with small strain phenomena. Yet, the effective stress and void ratio, both key determinants of sandy soil shear strength, are also primary factors affecting shear wave velocity. This stud…
