Numerical Investigation on the Influence of Combined Faults and Structural Features on Rock Burst Mechanisms

Anye Cao, Liu, Siqi Jiang , Qi Hao, Yujie Peng, Xianxi Bai and Xu Yang

Year: 2020 | Conference Paper | Publisher: Scitech Conference Xplorer

Abstract:

This study conducts a numerical investigation into the impact of combined faults and structural features on rock burst mechanisms. Rock bursts, a significant hazard in mining and tunneling operations, often result from the complex interaction of geological faults and structural features within rock masses. Using advanced numerical modeling techniques, we analyze the influence of multiple fault configurations and structural characteristics on the initiation and propagation of rock bursts. Through comprehensive simulations, we elucidate how the interaction between faults and structural features affects stress distribution, energy release, and failure mechanisms in rock masses. Our findings provide valuable insights into the underlying mechanisms of rock bursts, aiding in the development of effective mitigation strategies for enhancing safety in underground excavation operations.

Adaptive Fourth-Moment Reliability Analysis Method Based on Kriging for Engineering Structures

Shiyuan E, Yanzhong Wang, Bin Xie and Fengxia Lu

Year: 2020 | Conference Paper | Publisher: Scitech Conference Xplorer

Abstract:

This paper introduces an adaptive fourth-moment reliability analysis method for engineering structures, leveraging Kriging interpolation. Reliability analysis plays a critical role in assessing the safety and performance of engineering structures under uncertain conditions. Traditional methods often face challenges in accurately capturing the complex nonlinear behavior of structures, especially when dealing with high-dimensional input spaces. To address this, we propose an adaptive approach that combines fourth-moment analysis with Kriging interpolation to efficiently estimate reliability metrics. By iteratively updating the Kriging surrogate model based on available information, our method adapts to the underlying response surface, improving accuracy while reducing computational cost. We demonstrate the effectiveness of the proposed approach through numerical examples, highlighting its ability to provide reliable estimates of structural reliability with reduced computational effort. This adaptive method offers a promising tool for enhancing the reliability assessment of engineering structures in practical applications.

Structural Detection and Stability Monitoring of Deep Strata on Slopes: High-Density Resistivity Method and FBG Strain Sensors Integration

Chuan Li, Li Wei, Qiang Xu, Lubing Yang, Jiaqi Li and Xiaorong Wan

Year: 2020 | Conference Paper | Publisher: Scitech Conference Xplorer

Abstract:

This study presents a comprehensive approach for structural detection and stability monitoring of deep strata on slopes, integrating high-density resistivity method and Fiber Bragg Grating (FBG) strain sensors. Slope stability is a critical concern in geotechnical engineering, particularly in areas with complex geological conditions and deep-seated strata. Traditional monitoring techniques may lack the ability to adequately assess subsurface conditions and anticipate potential instability. In this research, we propose the combined use of high-density resistivity imaging and FBG strain sensors to enhance the understanding of subsurface structures and monitor slope stability in real-time. The high-density resistivity method offers detailed insights into the distribution of subsurface features, while FBG strain sensors provide continuous monitoring of deformation and stress changes within the slope. Through a case study, we demonstrate the effectiveness of this integrated approach in detecting structural anomalies and early warning of potential slope instability. This methodology provides a valuable tool for geotechnical engineers and practitioners to improve the management and mitigation of slope-related hazards.

Year: 2020 | Conference Paper | Publisher: Scitech Conference Xplorer

Abstract:

This research investigates the critical components influencing the binding activity and stability of the collagen-binding domain (CBD) within the Collagen-Binding Protein Cbm from Streptococcus mutans. The N1-domain, linker region, N2-domain, and latch play pivotal roles in mediating the interaction between Cbm and collagen, yet their specific contributions remain poorly understood. Through a comprehensive analysis, we elucidate the individual and collective impacts of these domains on CBD functionality. Utilizing biochemical assays, molecular dynamics simulations, and structural analyses, we discern the mechanisms underlying CBD binding activity and stability. Our findings shed light on the intricate interplay between these structural elements, providing valuable insights for the rational design of CBD-based therapeutics and biomaterials. This study advances our understanding of collagen-protein interactions and informs strategies for modulating CBD functionality in various biomedical applications.
