Abstract
This article studies the impact of geological environment on the stability of surrounding rock in tunnels, as well as the control and improvement measures. Firstly, the basic concepts and categories of tunnel engineering, evaluation indicators and methods for surrounding rock stability, and the impact mechanism of geological environment on surrounding rock stability are introduced. Subsequently, geological exploration and testing were carried out in the study area, and the geological data were analyzed and the stability of the surrounding rock was evaluated. Through determination of the mechanical parameters of the surrounding rock and stability analysis, it was found that the geological environment has a significant impact on the stability of the surrounding rock, including rock type, structure, and faults. Finally, based on the research results, the design principles and methods of the surrounding rock support structure were proposed, and stability analysis and acceptance were carried out. The results of this research show that the geological environment of tunnels is an important factor affecting the stability of surrounding rock and must be fully considered in engineering design and construction. At the same time, effective support structures and stability evaluation methods are also essential and can provide important references and guarantees for the safety and stability of tunnel engineering.
