Abstract
To overcome the drawbacks of insufficient measuring point of ground stress, it is necessary to invert the ground stress field by multiple linear regression method. Aiming at a deep-buried tunnel, according to the ground stress data measured by hydraulic fracturing method, the inversion of ground stress is carried out. Based on the introduction to the basic inversion theo-ry and error analysis, the inverted results of ground stress are provided. The results show that the calculated results by multiple linear regression is in accordance with the measured data, so it is feasible to be applied in the evaluation of ground stress in the presented tunnel section;due to the influence from horizontal tectonic stress and fracture structure, the ground stress in the pres-ented section reveals some spatial variability.关键词
