用力学的观点研究顺层岩质边坡失稳机理是顺层岩质边坡稳定研究的重要手段之一,顺层岩质边坡刚度对其稳定的影响获得了广泛的关注,在总结前人研究成果基础上,采用柔度作为其刚度指标,认为顺层岩质边坡力学模型、破坏形态以及临界长度与其柔度大小密切相关,在其柔度小于临界柔度值时,可简化为杆模型,在其柔度值大于其临界柔度值时,根据其实际坡长,可简化为梁或杆模型,并分析了柔度大小与其破坏特征之间的关系,指出溃屈破坏一般只在特定的情况下发生。
From the viewpoint of mechanics, it is one of the important methods to study the stability of bedding rock slope that the instability mechanism of bedding rock slope is one of the important methods. The impact of bedding rock slope stiffness on its stability has received extensive attention. Before concluding Based on the research results of people, using the flexibility as its stiffness index, it is considered that the rock mechanics model, the failure mode and the critical length of the bedding rock slope are closely related to their compliance. When their compliance is less than the critical compliance value, they can be simplified to When its compliance value is greater than its critical compliance value, the rod model can be simplified as a beam or rod model according to its actual slope length. The relationship between the compliance and its failure characteristics is analyzed. Occurs in certain circumstances.
