摘要
阐明了用控制致裂测试岩体应力的实质。介绍了控制致裂的基本理论，根据围岩控制致裂的原岩应力计算，利用３个方向的正应力实测值绘制应力椭圆。
This paper sets forth the essence of testing rock stress by fracturing controlit also introduces the basic theory of fracturing control,the virgin rock stress caculationwhich is used to control fracturing according to wall rock.Finally,it shows stress ellipsedrawing by use of normal stress value in three directionts.
