| 3D GEOSTRESS REGRESSION ANALYSIS METHOD AND ITS APPLICATION |
|
|
|
Abstract Initial geostress is one of the most important factors in geotechnical design and construction. According to in situ measurement，with 3D FEM regression analysis used，considering the gravity and con-
structional stresses of rock mass，and by using multivariate regression analysis principle，the initial stress field of the calculation area can be obtained. The geostress regression analysis results of a highway tunnel indicate that the calculated results are in a good agreement with the in situ measured data and can be used to engineering practice.
