Rockbursts are critical geohazards during the construction of deep buried tunnels under high in-situ stress conditions. However, their accurate predictions and effective mitigations remain challenging in complex geo-stress environments. This study utilizes an in-house combined finite-discrete element method (FDEM) to conduct a case study on the rockbursts observed in a deep buried railway tunnel in southwestern China revealing...

In recent years, unmanned surface vehicles (USVs) have gained increasing attention in industry due to their efficiency and versatility in marine operations. Artificial potential field (APF) methods, with their strong adaptability and simplicity of implementation, are widely used in USV path planning tasks. However, the naive APF method struggles in static complex environments, due to the local minima problem. Not to mention th...
