深钻孔地应力测量和地应力场分析及其应用

 本文叙述了深钻孔地应力测量技术和地应力场分析方法。深钻孔地应力测量可以根据工程和地质上的需要,测量不同深度的地应力状态,测量深度可达数百米。地应力场分析以大量的立体型实测数据和地质条件为依据,把有限个测量钻孔的不同深度的地应力实测资料,准确地扩展到大范围的工程区域。

Geostress Survey in Deep Borehole and Analysis of Geostress Field and its Application

This paper presents the measuring techniques of geostress in deep borehole and the analytic methods of geostress field. Based on the demands of projects and geology, the geostress measurement of deep borehole may be able to measure geostress states in different depths, and surveying depth can reach many hundreds of meters. On the basis of a large number of three dimensional type of measured data and the geologic conditions, the analysis of geostress field may be exactly extended measured data of geostress of limited measuring boreholes in different depths to project area in a large zone.
