Abstract

The invention discloses a self-consistent integration modeling method for a geologic body and a structural body. The method comprises the following steps: inputting geometric data of the geologic body and the structural body to be integrated in batches according to a body-surface-line-point format; preliminarily searching geologic body-structural body pairs with overlapped bounding boxes by adopting a bounding box method; carrying out the surface-surface overlapping and intersecting Boolean operation on the geologic body-structure body pairs overlapped in each bounding box; aiming at all the surfaces, establishing a geometric topological relation of directed surfaces-directed rings-directed line segments-vertexes; aiming at all the bodies, establishing a geometric topological relation of directed body-directed shell-directed surface; for each geologic body-structure body pair with the overlapped bounding box, giving a real overlapping state of the geologic body-structure body pair; and outputting to obtain an integrated geological-structure integrated model. According to the invention, a natural geologic body and a designed structural body can be conveniently and rapidly integrated together, a geologic-structure integrated model is efficiently provided for geotechnical engineering analysis, and self-consistent integration of the geologic body and the structural body is realized.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and disaster prevention and reduction engineering such as civil engineering, engineering geology, water conservancy and hydropower, transportation, etc., and specifically relates to a self-consistent integrated modeling method of geological bodies and structures, which is applicable to slopes, tunnels and foundations. Pit and other engineering modeling. Background technique [0002] With the urbanization of mountainous areas in our country, the construction of civil engineering, water conservancy and hydropower, transportation and other projects are in full swing. The essence of the construction of these projects is the development of natural geological bodies and the construction of artificial structures. For example, structures such as anti-slide piles in slopes, linings in tunnels, and retaining piles in foundation pits. Geological bodies and structures blend and coexist, depe...
