Abstract Deeply buried underground engineering often faced with a high geostress environment. Based on the research of the conception of “deep stratum” and “deep engineering”，through collecting about 600 groups of the measured geostress data in deep rocks of China mainland，the distribution of the vertical stress，the largest horizontal principal stress，the minimum horizontal principal stress and the lateral pressure coefficient varying with depth in Chinese mainland are shown in this paper. The features of the geostress in deep rocks are elementarily analysed refer to the analysis method of Hoek and Brown，the distribution rule of the vertical stress，the maximum and the minimum horizontal principal stresses with depth in deep stratum are regressive analysed，and trend of the lateral pressure coefficient with depth is also discussed.

Key words： rock mechanics geostress dispersed point chart lateral pressure coefficient
