A STUDY ON ROCK STRESS DETERMINATION BY BOREHOLES STRESS CHANGE MEASUREMENT USING CONTROLLED FRACTURING TECHNIQUE

为了寻求一种操作简单、低成本的岩体应力测试方法，本文提出了一个依据控制致裂钻孔应力变化的量测推算原岩应力的改进平行钻孔法。本文阐明了平行钻孔法岩体应力量测的特点和控制致裂法的原理。介绍了依据控制致裂钻孔应力变化确定岩体应力的基本理论。

To search a simple low cost method of rock stresses measurement, a improved parallel boreholes method of rock stress determination with use of controlled fracturing technique is proposed. In this paper the feature of parallel boreholes method for observation of rock stresses and the principle of controlled fracturing technique are described.A foundamental theory of rock stress determination by boreholts stress change measurement using controlled tracturing technique is presented.
