Key block theory is a widely used method in rock engineering for analyzing the stability of
fractured rock masses. However, the traditional theory does not consider the forces between …

The geometry of discontinuities in a rock mass is one of the most important influences on the
behavior and characteristics of that rock mass. The geometry of discontinuities largely …

Purpose. Discontinuities in rock masses are natural fractures that delimit various block
shapes and sizes, which can fall, slide or topple from the excavation and collapse under …

One of the important pre-processing stages in the analysis of jointed rock masses is the
identification of rock blocks from discontinuities in the field. In 3D, the identification of …

In traditional block theory, the removability and stability of rock blocks are analyzed
independently; that is, the stability of a removable block is analyzed in detail, and …

Seismic stability analysis of a rock block is an important issue in the field of rock mechanics
and rock engineering. To solve this problem, the block theory and the Newmark method are …
