Abstract: The failure mechanisms of unreinforced and reinforced layered rocks with various layer dip angles were analyzed using acoustic emission (AE) activities, failure modes, and load–displacement responses. The results indicate ...

Abstract: A concrete-filled steel tubular (CFT) yieldable support is proposed as a new passive support system in deep tunnels to improve the stability of soft rock mass, which consists of a CFT arc, a porous metal connector, and a ...

Abstract: Recently, a new plating system was proposed based on a strain localization mechanism for addressing the critical debonding problem in externally bonded reinforcing systems for reinforced concrete (RC) structures. The system ...

Abstract: Vibration responses of nonlinear or timevarying dynamical systems are always nonstationary. Time–frequency representation becomes a necessary approach to analysis such signals. In this paper, a nonstationary vibration ...

Abstract: Unstable cavitation presents an important speed barrier for underwater vehicles such as hydrofoil craft. In this paper, the authors concern about the physical problem about the cloud cavitating flow that surrounds an ...

Abstract: Safety coefficient and surface settlement were chosen as evaluation indictors for non-self-stabilizing weak strata and basic self-stabilizing weak strata. Fluid mechanical interaction is used to analyze the pre-reinforcement ...

Abstract: Deep excavations in congested urbanized areas may have a significant impact on existing structures. Therefore, protective measures must be taken to control wall deformations and related soil movements. However, little is ...

Abstract: Compared with recirculation and injection modes, once-through direct steam generation (DSG) parabolic troughs are simpler to construct and require the lowest investment. However, the heat transfer fluid (HTF) in once-through ...
