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: Excessive lateral movements of buried pipes in geohazard-prone areas frequently jeopardize the structural integrity and serviceability of pipelines, as well as the safety of the surrounding geoenvironments. Based on the ...

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: This study investigated the behavior of a 38-m deep twin circular peanut-shaped cofferdam interconnected with a rectangular section for cut-and-cover tunnel construction using distributed fiber-optic sensors (DFOSs) based ...

Abstract: Soil nailing has become a common method for improving slope stability due to its cost-effectiveness and easy installation. However, concerns have been arisen regarding the quality and integrity of soil nailing works. This ...

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 ...
