A new method for analysis on geo-stress field fitting Ping Shi 1,2a, Zhang-hua Chen 1b, Hong-guang Ji 3c 1 School of Mathematics and Physics，University of Science and Technology Beijing，Beijing 100083，China， 2 School of science, Beijing University of Civil Engineering and Architecture，Beijing 100044，China, 3 School of Civil and Environmental Engineering，University of Science and Technology Beijing，Beijing 100083，China asp@bucea.edu.cn, b chenzhanghua@ustb.edu.cn, c jihongguang@ces.ustb.edu.cn Keywords: partial least squares; geo-stress field; correlation; regression analysis Abstract.
Therefore, based on measurement information in the field geological materials (such as ground stress, elastic modulus, poisson's ratio, density, etc.) to inversion of in-situ stress data, and by adopting the method of partial least-squares regression parameters for rock mass was analyzed, its usefulness to solve geotechnical engineering opened a unique way to calculation parameter selection.By using PLSRM,the problems could be solved such as less sample points and strong correlation between the independent variables, and the fitting value could be obtained, that was used to establish the relationship between the independent variable and dependent variable.
In mining engineering, in order to obtain data of underground geotechnical material and the stress distribution, sampling and measuring buried points under ground must be carried out.

Because bottom framework materials of the structure is different from the upper materials of brick-concrete, resulting in discontinuous structural strength and stiffness, which will cause excessive stress concentration at local weak parts, seismic performance of the structure is poor.
At the same time, there had also unqualified construction materials, such as cement grade and steel’s not meeting standard.
