DECIPHERING THE DYNAMICS: MECHANISMS AND CONTROL STRATEGIES FOR LARGE DEFORMATION IN CARBONACEOUS SHALE TUNNELS

Abstract

Carbonaceous shale, a robust and weather-resistant rock composed of clay and minerals, plays a crucial role in tunnel engineering due to its high hardness and strength. This study delves into the utilization of carbonaceous shale as a support structure in tunnel engineering, emphasizing its capacity to mitigate the risk of collapse and deformation in tunnels. The rock's properties make it an ideal choice for ensuring the structural integrity and safety of tunnels [1].

In tunnel engineering, carbonaceous shale serves as a vital component to fortify the tunnel structure, minimizing the potential for collapse and deformation [2-3]. Various methods, including foundation strengthening, lining reinforcement, and installation of lining templates, are employed to enhance the rock's supportive capabilities [5]. Despite its inherent robustness, carbonaceous shale is susceptible to damage, necessitating meticulous attention to maintenance and upkeep during usage [6-7].

This research focuses on unraveling the mechanism and control of large deformation in carbonaceous shale tunnels. Understanding the factors influencing deformation is pivotal for implementing effective measures that contribute to the longevity and safety of tunnels, particularly in the context of high-speed rail construction. Investigating the behavior of carbonaceous shale under different conditions and stressors is paramount for formulating strategies to mitigate deformation risks and enhance the resilience of tunnel structures [4].

The findings of this study provide valuable insights into the maintenance practices and control mechanisms required to ensure the continued efficacy of carbonaceous shale in tunnel engineering. By comprehending the complexities of large deformation in carbonaceous shale, engineers and researchers can develop targeted solutions to enhance safety standards in tunnel construction, especially in high-speed rail projects. This research contributes to the broader understanding of geological materials used in construction and lays the groundwork for improved practices in utilizing carbonaceous shale for enhanced tunnel stability.
