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。 This article describes the deep borehole stress measurement techniques and ground stress field analysis methods. The deep borehole stress measurement can measure the ground stress state at different depths according to the needs of engineering and geology, and the depth can reach hundreds of meters. The analysis of the ground stress field is based on a large number of three-dimensional measured data and geological conditions, and accurately expands the measured data of ground stress at different depths of a limited number of boreholes to a large-scale project area.
