Water sealing performance is important for underground water-sealed oil storage (UWSOS). The key issues concerning water mainly include the permeability of fractured rock mass (FRM), safety (WSS), curtain performance, and prediction control inflow. This paper reviews progress above four on performances. First, an FRM basis several commonly used test methods spatial variation characteristics are outlined. Second, current criteria compared, evaluation WSS summarized. Third, design parameters...
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,...
Coal mass strength estimation has attracted broad attentions for decades. Investigating the effect of scale and anisotropy on Uniaxial Compressive Strength (UCS) via P-wave velocity is crucial in upscaling lab-obtained correlation to coal evaluation. Microstructures were considered as major impact factors difference mechanical properties coal. Thus, microstructure correlated influence specimen sizes angles UCS based primary wave (P-wave) investigated here. Specimens with four diameters (25...
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,...
Given traditional concrete’s brittle fracture and performance limitations in transportation infrastructure, this paper innovatively introduces rubber particles, polypropylene fibers, bentonite, polymer emulsion into new flexible concrete. It uses an orthogonal test method to optimize its mix ratio design. The influence mechanism of each modified material content on the concrete is deeply explored. key factors their primary secondary effects improving compressive, tensile peak strain,...
The lined high-pressure gas storage cavern has the advantages of high extraction rate and strong circulation capacity, can withstand higher internal pressure. It overcomes many shortcomings traditional compressed air energy systems a wide application. This paper takes three most important layout parameters including depth, inner diameter space as influencing factors uses ABAQUS finite element software to design simulation conditions based on orthogonal test single-factor experiment....
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...
The AlCoCrFeNi-WC-Ti composite coating exhibits excellent hardness and wear resistance, derived from the various strengthening mechanisms. An accurate prediction model is crucial for analyzing contribution.
