摘要
为了解决高岩体应力的套筒致裂法测试的难题，提出了高应力场的应力测试方法及原岩应力的计算方法。介绍了平行钻孔一套筒致裂岩体应力测试法及其基本假设与公式，给出原岩应力的计算方法，讨论与分析了岩体应力的量测结果。
To solve the knotty problem of high rock stress measurement by sleeve fracturing technique,a means of measuring stresses in high stress field and calculation on initial rockmass stresses are proposed. This paper describes the substance of parallel boreholessleeve fracturing technique for rockmass measurement,the foundational assumptions and formulas as well as process of calculation on initial rockmass stresses. Measuring results and their analyses are presented.
