Embodiment Construction

[0025] The specific implementation method of this method can be described as follows in conjunction with the accompanying drawings and examples.

[0026] There are 13 monitoring lines in the west and north sections of the open-pit mine, and 51 monitoring points in dangerous areas. There are 40 periods of observation data from April 2005 to July 2008. As time goes by, some of the monitoring points are destroyed due to large deformation and other reasons. According to the needs of the slope treatment project, the short-term and long-term predictions of the three-dimensional solid deformation of the slope are carried out respectively.

[0027] The detailed steps for short-term prediction of 3D solid deformation are as follows:

[0028] 1) Model parameter sequence calculation. According to the horizontal displacement monitoring data of 40 periods, the deformation value of the slope monitoring point was fitted with cubic surface, and the model parameters were estimated by the lea...

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...
