摘　　要：基于花岗岩蚀变带岩体的强度与稳定性评估展开深入探讨,旨在揭示蚀变对岩体物理力学性质的影响,并对其强度与稳定性进行定量化分析。通过细致的理论分析,研究了蚀变带岩体在不同蚀变程度下的强度变化规律及其对岩体稳定性的影响。研究表明,蚀变不仅改变了岩体的矿物成分和结构,还导致其强度显著下降,并对岩体的稳定性产生不利影响。特别是在复杂的应力条件下,蚀变带岩体更易发生失稳破坏。在总结蚀变对岩体力学性能影响的基础上,提出了一套强度与稳定性协同评估方法,为未来在工程设计中更好地应对蚀变岩体提供了理论支持和技术参考,具有重要的应用价值和理论创新意义。Based on the evaluation of the strength and stability of granite alteration zone rock mass,this study aims to reveal the influence of alteration on the physical and mechanical properties of rock mass,and quantitatively analyze its strength and stability.Through detailed theoretical analysis,the strength variation law of the rock mass in the alteration zone under different degrees of alteration and its impact on the stability of the rock mass was studied.Research has shown that weathering not only changes the mineral composition and structure of the rock mass,but also leads to a significant decrease in its strength and has adverse effects on the stability of the rock mass.Especially under complex stress conditions,rock masses in weathering zones are more prone to instability and failure.On the basis of summarizing the influence of weathering on the mechanical properties of rock masses,a set of strength and stability synergistic evaluation methods is proposed,which provides theoretical support and technical reference for better response to weathering rock masses in engineering design in the future,and has important application value and theoretical innovation significance.
