| 摘 要： | 钻孔崩落法是地应力测量的一种重要方法，但是考虑到岩石力学性质的非均匀性，崩落方法角会偏离最小主应力方向。用Weibull分布来描述岩石力学性质的离散性，用RFPA方法对非均匀岩石的钻孔崩落方位角进行了模拟。通过对模拟结果的分析，研究了非均匀岩石钻孔崩落方位角的分布情况。指出了RFPA方法进一步应用的前景。

| Abstract: | Bore hole breakout is an important method to measure the orientation of earth stress. For inhomogeneous rocks, actual orientation of break out usually deviates from the minimum compressional stress predicted by idealistic elasticity. We use a Weibull distribution to describe the scatter of mechanical property of rocks, and apply the RFPA method to simulate the bore hole breakout in inhomogeneous rocks to study their orientation distribution and possible errors. It is also shown that the RFPA method has broad future of application. |
