Geometric Cross-Scale Back-Analysis and Reconstruction Method for Complicated Geo-Stress Field
摘要
Abstract
In order to overcome the problems in geo-stress measurement due to high cost, long cycle, and data discrete, the cross-scale calculation method of a complicated geo-stress field is put forward by making full use of limited measured geo-stress data. A mathematical model of multivariate linear regression is proposed for back-analysis of the geo-stress field. This method can realize the reconstruction of a numerical model from large-scale elements to small-scale elements. The geometric cross-scale model-building technology and method are developed from global to local geo-stress field. As a result, an auto-regression, back analysis and reconstruction of the geo-stress field are performed based on the limited measurement data in site. The research shows that the calculated stress values agree well with the observed values, indicating that the proposed method of auto-regression, back-analysis, and reconstruction of complicated geo-stress field is reasonable and feasible, and the calculated results are reliable.关键词
