The structural stability of engineering rock mass under dynamic disturbance is directly associated with the fracture mechanics properties in practice. Fully understanding rock’s mechanical behavior and crack evolution caused by stress concentration at tip load can offer useful insight into mechanism. A test using split-Hopkinson pressure bar (SHPB) system was performed on a single prefabricated fissure sandstone centrally cracked Brazilian disk (CCBD) specimens. Based theory one-dimensional...
In order to study the impact of blasting vibration subway tunnels on adjacent buildings, taking tunnel mining method construction section between Zhifang Street Station and Metro Town Wuhan Line 27 as engineering background, scheme is optimized by reducing maximum single charge, multi-section densifying surrounding holes. The HHT wavelet analysis are used evaluate advantages disadvantages optimization from perspective energy. results show that peak velocity significantly reduced frequency...
This study designs and uses water-borne epoxy resin (WBER) curing agent (CA) to modify traditional cement-based grouting for tunnels. The purpose of this paper is analyze the rheological mechanical properties composite with different ratios WBER CA modification mechanism by means chemical characterization explore feasibility as a high-performance modifier tunnel construction. prepared mixing cement paste polymer emulsion. A series experiments was carried out investigate effects CA, including...
Deep mine rocks are often subjected to rock burst induced by dynamic load. The existence of initial holes will reduce the mechanical properties and affect stability safety tunnel excavating. In order study effect ratios inner outer diameter on disc specimen failure modes, we use cylindrical sandstone specimens Φ50 × 25 mm process center different diameters, a series splitting test were carried out with system split Hopkinson pressure bar (SHPB) when is 0.15 MPa, 0.3 0.5 MPa. results show...
Aiming at the dynamic mechanical properties of weakly cemented fine sandstone in rich water‐bearing strata western China under loading, a 50 mm rod diameter separation Hopkinson pressure bar (SHPB) test was used to study Paleogene coal mine Ningxia. The system carried out impact compression tests −15°C, −20°C, and −30°C average strain rate 28 s −1 –83 obtained compressive strength frozen specimens different conditions. curve fracture morphology were analyzed for relationship between peak...
To mitigate potential damage to RC structures subjected impact load—especially spalling damage—engineered cementitious composite (ECC) is applied, with the aim of reinforcing members, so as improve their performance. In present study, response beams, and without ECC reinforcement, loading was investigated. Firstly, mechanical properties were characterized by quasi-static compression tension tests, well dynamic direct tests. Then, K&C model (Karagozian Case Concrete Model) employed...
The quantity estimation of cargo is great significance for the scientific management storage. traditional statistics based on RFID technology to obtain information in circulation, which time-consuming, laborious, and complicated. Due unsatisfactory accuracy, computer vision-based statistical methods are not widely used field statistics. To solve above problems, this paper proposes a method estimating storage CSwin-Unet XGBoost, improves accuracy while reducing equipment dependency. Firstly,...
