RISExperimental Study on the Dilatancy Characteristics and Equation of Saturated Sand–Gravel Composites during the Whole Shearing Process
Publisher: ASCE
Abstract: The dilatancy equation plays an important role in establishing the elastoplastic model for sand–gravel composites. However, the equation is not comprehensive in its considerations. In this paper, experimental investigations ...
Prediction of Pressure Pulsation for the Reciprocating Compressor System Using Finite Disturbance Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure pulsations in the piping system of the reciprocating compressor produce excessive noise and even lead to damage in piping and machinery. Therefore, it is very important to predict ...
KF-Based Multiscale Response Reconstruction under Unknown Inputs with Data Fusion of Multitype Observations
Publisher: American Society of Civil Engineers
Abstract: Utilization of multitype measurements including local and global information for structural health monitoring (SHM) has typically outperformed that using solo-type measurements. However, in many practical situations, only ...

Solution of the Ultimate Bearing Capacity at the Tip of a Pile in Anisotropic Discontinuous Rock Mass Based on the Hoek–Brown Criterion
Publisher: ASCE
Abstract: An analytical method will be proposed to investigate the bearing mechanism of piles in an anisotropic discontinuous rock mass. Based on the characteristic line method, the discontinuous part of the rock is considered as ...
Multiobjective and Joint Operation Model for Multistakeholder Cascade Hydropower System
Publisher: ASCE
Abstract: Involvement in the operation of a multiobjective and multistakeholder hydropower system requires balancing conflicting objectives and coordinating economic gains to achieve a win–win situation through joint operation. This ...
Rockfill Particle Breakage Generated by Wetting Deformation under the Complex Stress Path
Publisher: ASCE
Abstract: Wetting deformation of the rockfill material, which is generated by particle sliding, breakage, and rearrangement, plays a vital role in earth-rockfill dam deformation that determines the safety of the dam. However, the ...
Dynamic Reliability Analysis of the Stability of the 3D Slope of a Rockfill Dam Based on the Copula Function and Generalized Probability Density Evolution Method
Publisher: ASCE
Abstract: Rockfill strength parameters are important indicators of the stability of a rockfill dam slope. Therefore, a rational representation of the distribution characteristics of these parameters is extremely important to accurately ...
Parameter Identification of Main Cables of Cable Suspension Structures Based on Vibration Monitoring of Cable: Methodology and Experimental Verification
Publisher: ASCE
Abstract: This paper focus on parameter identification of the main cables of cable suspension structures. Based on the dynamic stiffness theory, an inverse analysis characteristic function (IAC function) for identifying the main ...
Numerical Simulation and Stability Investigation on the Excavation Process of Multistage High Steep Slope
Publisher: ASCE
Abstract: Using UDEC discrete-element method (DEM) and field monitoring method, the influence rules of slope height, slope angle, and excavation stage on the stress field, displacement field, and stability safety factor of high steep ...
