Deformation prediction method for slope three-dimensional entity

Abstract

The application of the method relates to the field of exploitation of the open pit mine and side slope engineering management and the like. With the integration of the research result on single model prediction, the research result on combined model prediction, and the research result on overall deformation prediction of a side slope monitoring line, a deformation predication method for the side slope three-dimensional entity is provided; the deformation predication method skillfully combines a static modeling method with a dynamic method, thus solving the difficulty in the overall prediction of the slope three-dimensional entity; with the deformation prediction method for the slope three-dimensional entity, the deformation condition of the side slope in long time can be predicted; simultaneously, a gray system model and a time sequence ARMA (Autoregressive moving average model) are adopted in predication, a precise predication result is obtained; and the comprehensive research on the long-time deformation predication of the side slope three-dimensional entity refers to the comprehensive application of four methods such as the deformation predication, the long-time predication, the single model predictionand the rolling combination predication of the side slope three-dimensional entity, the predicting outcomes has very high reliability.

Description

technical field [0001] The method relates to the field of geotechnical engineering, in particular to the fields of open-pit mining and slope engineering treatment, and specifically relates to the principle and method of predicting the deformation of a slope unit entity. Background technique [0002] At present, there are many methods for predicting the deformation of slope entities, but most of these methods are two-dimensional prediction methods, which cannot fully and intuitively reflect the deformation of the three-dimensional entity of the slope, and cannot provide reliable information for the treatment of open-pit mine slopes. basis. [0003] Long-term monitoring of slopes in open-pit mines can enable mining companies to accumulate a large amount of historical records of slope displacements, thus providing a sufficient database for the research of 3D deformation prediction methods for slope entities. Contents of the invention [0004] The purpose of the present inven...
