| 摘 要： | 在深层地应力测量中，水压致裂法是最有效的测量方法。本探讨了该方法的几个关键性问题，例如压裂特征参数的取值，三维地应力测量，压裂缝的方向，破裂准则和钻孔轴向秒是主应力的一个方向等问题。

| Abstract: | The hydrofracturing technique is the most effective measuring method in the geostress measurement in deep stratum. In this paper, some questions about the method are discussed, such as, determination of characteristic parameters of pressure fracturing, three-dimensional geostress measurement, direction of breaking fracture, fracturing criterion and axial direction of borehole which is not a direction of principal stress and others. |
