摘要
在不同方向的３ 个钻孔内进行常规水压致裂试验测量三维地应力的基础上，引入原生裂隙重张试验测量，提出了３ 种三维地应力测量的原理和方法。这些测量方法能适用于各种布置形式的单孔、双孔和多孔的测量，其中的两种方法也适用于深钻孔的三维地应力测量。
On the basis of 3 D geostress determination with the conventional hydrofracturing test in three boreholes whose directions are not the same, the measurement of re opening test for preexisting fissures in the boreholes is introduced, and the principles and methods of three 3 D geostress determination are suggested. These methods are applicable to 3 D geostress determination in single and multiple boreholes with various arranging forms. The two methods among them are applicable to 3 D geostress determination in deep borehole as well.
