This study presents a field-scale simulation of the Hongshiyan landslide in China. It uses an advanced numerical approach (material point method (MPM)) and constitutive model (the Drucker–Prager + μ(I) rheological relation) for three-dimensional (3D) simulation. The performance developed MPM is validated with laboratory-scale experimental data on granular collapse before being applied to analyses. ArcGIS are used create 3D soil body complicated geometry. Although can describe multiple phases...
When a load is applied to dense granular material, the stress largely transmitted by relatively rigid, heavily stressed chains of particles forming sparse network larger contact forces. Force act as key determinant mechanical properties such stability, elasticity and flowability. To understand structure evolution force chains, related physical processes three corresponding characteristic time scales are analyzed in this study. We also propose dimensionless numbers for measurement relative...
As a low cost and maintenance energy-absorbing device, tuned liquid damper (TLD) is being widely used to suppress structural vibration. In this paper, the real-time hybrid simulation (RTHS) employed investigate performance of TLD for controlling seismic responses actual multi-story structures, where experimentally modeled as physical substructure structure numerically simulated numerical substructure. Taking advantage RTHS technique, methodology achieving full-scale experiments developed...
In high-mountain canyon regions, many settlements are located on large, deep-seated ancient landslides. The deformation characteristics, triggering mechanisms, and long-term developmental trends of these landslides significantly impact the safety stability communities. However, mechanism under influence human engineering activities remains unclear. SBAS-InSAR (Small Baseline Subset-Interferometric Synthetic Aperture Radar) technology, UAV LiDAR, field surveys were utilized in this study to...
In order to solve the shortcomings of existing garlic sprouts extraction machine and lack cutting machine, a monomer road adaptive was designed based on technical characteristics topping machine. The entire consists mainly motion device, transmission device. Taking into account working process main parameters, structure size parameters each component have been designed, static analysis modal were carried out by ANSYS. maximum stress strain positions values frame determined through ANSYS...
SUMMARY A nonlinear finite element model for earthquake response analysis of arch dam–water–foundation rock systems is proposed in this paper. The includes dynamic dam–water and dam–foundation interactions, the opening contraction joints, radiation damping semi‐unbounded foundation rock, compressibility impounded water, upstream energy propagating along reservoir. Meanwhile, a new equivalent force scheme suggested to achieve free‐field input model. effects mechanism, joint opening, water...
In this paper, an approximately incremental dynamic analysis (IDA) is presented for seismic performance assessment of arch dams. The nonlinear dams involves the effects contraction joint opening, cracking concrete and foundation radiation damping. Three damage measures, i.e. maximum depth on dam–foundation interface extent in upper portion dam, associated with IDA curves are suggested to identify levels Dagangshan dam (210 m high) under construction China used as case study. Although there...
Using concrete as a thermal energy storage (TES) material is promising option for large-scale solar-thermal resource development and utilization. Specific heat one of the most important characteristics TES performance. In this paper, half-open dynamic method based on mixing principle proposed applied to measure concrete-specific at temperatures up 600 °C. Measurement specific corundum ceramic (99% Al2O3) first performed, test results illustrate accuracy efficiency method. Furthermore, tests...
