STUDY OF THE DISTRIBUTION OF IN-SITU STRESS AND ROCKBURST FORECAST FROM AHEHE TO MAKEHE OF SOUTH-TO-NORTH WATER TRANSFER WEST ROUTE PROJECT
The tectonic activities are much stronger in areas of South-to-North Water Transfer West Route project with complicated engineering geological conditions. It is most important to study in-situ stress for the project design. In terms of the measurement values of in-situ stress, the model, which describes the relationship between in-situ stress and the depth, can be set up, and regression equation can be obtained. Uniform experimental design was adopted, with only two infinite drill measurements being taken on in-situ stress; all possible factors considered, the most optimal regression equation can be reached in terms of the least variance. According to the characteristics of high in-situ stress, comparisons have been made between engineering rock grading and the Russenes method, Hoek method, and the optimal method for rock burst and assessment have been presented.
