本文根据500个塌方实例,经整理、归类、分析而成;概括了三大类岩体,不同塌方高度的地下洞室围岩塌方;就围岩塌方的影响因素、塌方机理作了分析论述,特别对塌方机理进行了有限元法的反演计算,为研究地下洞室围岩稳定提供了有价值的依据.本文还建立了塌方高度与围岩分类之间的数学关系式。此外,对围岩完整性各判别指标间的相关性作了有益的探讨。
Based on the 500 landslide examples, this article is organized, classified and analyzed. The landslides of the surrounding rock mass of underground caverns are summarized in three types of rock masses and different landslides. The influencing factors and landslip mechanism of landslides are analyzed and discussed In particular, the inversion calculation of the landslide mechanism by the finite element method provides a valuable basis for studying the stability of the surrounding rock in underground caverns.This paper also establishes the mathematical relation between the height of the landslide and the classification of the surrounding rock. In addition, the correlation between the discriminant indexes of surrounding rock integrity is discussed.
