Geological block objectification modeling analysis method

Abstract

The invention discloses a geological block objectification modeling analysis method. The method comprises the steps of S1, geological block objectification definition, S2, geological block automatic modeling and S3, geological block modeling analysis. The principle of the method is as follows: step S1, taking a geological block body as an aggregate formed by an individual or a plurality of geological sub-block bodies, and performing objectification definition; s2, dividing the rock mass into a plurality of geological sub-blocks by generalized extension of the geological structure surface, thenatural free surface and the manual excavation surface, and automatically generating a geological block model of the rock mass; and S3, directly extracting geometric and mechanical parameters of the geological structure surface from the model, carrying out stability analysis and calculation, and outputting an evaluation report, a chart and the like. According to the invention, the geological blockis regarded as an organic system; the composition, attribute and spatial relationship of the geological block are objectively expressed, the stability of the rock mass is judged, the safety coefficient of the rock mass is calculated, and a scientific basis is provided for advanced prediction of construction geology and adjustment of designed support parameters. The invention is mainly applied torock caverns, side slopes and foundation pit engineering in the field of geotechnical engineering.

Problems solved by technology

However, a large-scale slope project may have dozens of geological blocks intersecting. It is difficult to describe the real complex rock mass conditions and engineering impacts in two-dimensional maps and analysis reports. The manual geological analysis and data compilation workload is extremely heavy and very challenging. It is difficult to improve the spatial analysis and calculation evaluation ability of geological personnel, the quality of geological block stability analysis results, and work efficiency
