Concrete's dynamic performance and energy dissipation are critical areas of interest that significantly influenced by strain rate aggregate content. This study investigated concrete's deformation, strength development characteristics from specimens containing 0, 32%, 37% 42% aggregate. These were subjected to impact compression tests using a split Hopkinson apparatus, which allowed the effects content on concrete be analysed. The results show exhibits deformation hysteresis under loading,...
The current formula of critical hydraulic gradient is not adapted to solve cohesive soil. Assume that the seepage failure mode soil foundation was cylindrical or inverted circular truncated cone, based on calculation Terzaghi, analytical considering influence shear strength derived. Then, process clay layer simulated numerically, and effects thickness, radius, indexes slope were analyzed. comparison results show numerical test are in good agreement with calculated new formula. In addition,...
In order to study the compressive deformation and energy evolution characteristics of concrete under dynamic loading, impact compression tests with velocities 5, 6, 7 m/s were carried out on samples aggregate volume ratios 0, 32%, 37%, 42%, respectively, using a split Hopkinson pressure bar test apparatus. The broken pieces after destruction collected arranged. fractal fragmentation distribution specimens different rates discussed, roughness fragment surface was characterized by dimension...
In order to study the permeability characteristics of cohesive soil in consolidation process more accurately, this work, pores occupied by combined water were defined as invalid pores, and effective ineffective decoupled relationship between coefficient. The widely used empirical formulas coefficient modified, suitable for obtained.
