Abstract: In this study, a novel effective stress cell based on fiber Bragg grating (FBG) sensing technology is developed for direct measurement of effective stress in saturated soil. The primary concept of direct measurement is ...

Abstract: Stone columns (SCs) and sand compaction piles (SCPs) are widely utilized as effective methods to increase the bearing capacity and reduce the settlement of soft ground. In this study, a physical model test was conducted ...

Abstract: Study on the mitigation of debris flows and rockfalls is a very challenging topic due to complex moving and impacting mechanisms. A large-scale physical model is preferred by researchers in the study of debris flow and ...

Abstract: Flexible barriers have been proven to be effective measures for mitigating natural hazards, such as rockfalls, gravel flows, and debris flows. This paper presents a new numerical ring model based on the discrete element ...

Abstract: Flexible barriers trap large particles and boulders in debris flow but allow slurry and small particles to pass through. Field tests and real cases indicate that a certain amount of slurry and small particles in debris ...
