Finite-element analysis, monitoring and support method of soft-rock slope stability

Abstract

The invention discloses a finite-element analysis, monitoring and support method of soft-rock slope stability. The method includes the following steps: step one, obtaining rock slope failure types, slope stability influence factors and slope reinforcement support measures by induction, establishing a mechanical model of engineering geology simulation analysis under the action of the different influence factors, and analyzing a dominant factor controlling the soft-rock slope stability and a potential mode thereof; and step two, using an approximate equivalent physical model, which is formed bya plurality of mutually associated unit bodies, by a finite-element analysis method of the slope stability to replace actual structures or continua, and establishing equations, which characterize force and displacement relationships, through basic principles of structure and continuum mechanics and physical characteristics of units. The finite-element analysis, monitoring and support method of thesoft-rock slope stability uses the finite-element method to analyze the stability thereof, carries out support and treatment on places where danger may further occur, and has certain guiding significance for solving slope stability problems.

Description

technical field [0001] The invention relates to the field of slope stability, in particular to a method for finite element analysis, monitoring and support of soft rock slope stability. Background technique [0002] The stability analysis of slope engineering began in the 1950s and has been an important research content in the field of geotechnical and mining engineering. Foreign scholars began to study this issue earlier. Gudehus, G. and other scholars studied the three-dimensional stability and deformation of open-air slopes in 1972. The British Hawke's "Rock Slope Engineering" and "Rock Slope Engineering" published in 1974 In 1977, Canada published "Open-pit Mine Slope Handbook", which had a great influence on the research of open-pit mine slopes in my country. The Institute of Geology, Chinese Academy of Sciences, combined engineering geology and rock mechanics, emphasized the influence and control of geological conditions and geological structures on slope stability, an...

Problems solved by technology

[0003] Judging from the research results at home and abroad, the research dynamics in this field pay more attention to the calculation method of slope stability, while the research on the deformation law and stability control of deep and large open pit soft rock slopes considering time and space effects Few, the research on the deformation evolution mechanism, space-time characteristics and stability control of high and steep soft rock slopes under the interaction of complex mine structure and complex environment is not deep enough and systematic enough
