Problems solved by technology

The two-dimensional simplification facilitates the implementation of the calculation process, but it also ignores many factors that are critical to the stability of the rock mass, such as the constraint force of the lateral boundary
[0008] However, this technical solution does not realize the mechanical stability analysis of complex failure modes, and it cannot realize the analysis of n interfaces and the establishment of mathematical models

Abstract

The invention discloses a modeling method suitable for rock mass, which includes the following four steps: parameter preparation, vertex coordinate calculation, polygon surface construction and geometric element calculation. The present invention adopts a method mainly based on solving equations, and absorbs the finiteness judgment in the block theory in the existing method and the polygonal search technology in the structural surface network simulation. It is different from the vector operation-based method in block theory. Stability analysis with mechanics for more complex failure modes.

Description

technical field [0001] The invention belongs to the field of solid structure modeling and analysis of rock mass engineering such as geotechnical engineering, mining, engineering construction, water conservancy engineering, underground structure, etc., and particularly relates to a process based on discontinuous medium, anisotropic rock mass, and engineering disturbance Three-dimensional numerical simulation analysis method and engineering application. Background technique [0002] The limit equilibrium analysis method is a traditional rock mass stability analysis method that has been used up to now. Generally, this analysis method uses a simplified description of the geometric model of the rock mass in the form of a two-dimensional section. The two-dimensional simplification facilitates the implementation of the calculation process, but it also ignores many factors that are crucial to the stability of rock mass, such as the constraint force of the lateral boundary.
