Three-dimensional Modeling Of The Geology Body And Engineering Application

The geological phenomena of nature are extremely complicated; the traditional plane exploration figure can't express them well, and isn't responding to the request of engineers and technicians. With the development of modern project to the high and great, the geological phenomena of project become more and more complicated, so the three-dimensional modeling of the geological body becomes more and more urgent. The geological structure simulation of the three-dimension can express the complicated geological structural configuration, and reflect the spatial relationship among the structural elements. The visual three-dimensional simulation of the geological body makes the display of the geological body truer, more vivid, more accurate and clearer. With the deepening that scientific and technical personnel study about geology, with the gradual improvement and perfecting of the computer figure application level, the three-dimensional modeling of the geological body become possible. And in recent years, popularize of computer application in geological project have promoted the development of three-dimensional geology modeling greatly even more. Visualization of the geological three-dimension is an important means to correctly know the geological structure that, it is the foundation stone of the modern geological project applying, its application prospect is quite wide.This text uses IDL (Interactive Data Language) as the developing platform in the modeling and analysing of visual three-dimension geological figure. According to the actual demand of project application, This text imitate such geological structure of project yardstick as fault, bedding plane and great joint etc with radial basis function neural network, and construct out the geological model figure of the three-dimension. The three-dimension geological model figure that is imitated can show under rotating and cutting according to user's needs. On the basis of three-dimension geological model figure that have set up, this text Analyses and calculates to a piece of body stability question of country rock of underground hole room, Analyses and calculates to the question of searching for the split surface whose shearing strength is minimal in rock slope and solving safety coefficient of stabilizing to the surface having searched. And this text has worked out the corresponding computer software to these two kinds of common projects.utilizing block theory, this text make a stable analysis to orient block, half orient block and random block in country rock of underground hole in low stress, solve key block in the country rock of hole room, and do stability check to the firming measure of systematic anchor that has already been designed, and have put forward the corresponding handling suggestion to the unqualified part for consulting while constructing, guaranteeing construction of the project engineering's security.This text explains how to search for the split surface whose shearing strength is minimal in rock slope joints and cracks generated, with simulated annealing algorithm, in detail, and how to solve safety coefficient of stabilizing of minimum shearing strength split surface having searched for with improved Sarma algorithm.
