This proposal presents a comprehensive study of rock anisotropy and the nature of the stress field induced in anisotropic rock masses with irregular topographies consisting of ridges and valleys. The first task of the proposed research is analytical and consists of deriving closed-form solutions to investigate the combining effect of rock stratification and topography on in situ stresses. The second task consists of testing a variety of anisotropic rocks under uniaxial, triaxial and true triaxial conditions to determine their range of elastic properties. The third task is to conduct dilatometer tests to determine the deformability properties of anisotropic rock masses in the field.

这一建议对岩石各向异性和由山脊和山谷组成的不规则地形各向异性岩体中诱发的应力场的性质进行了全面的研究。拟议研究的第一个任务是分析，包括推导闭合形式的解，以研究岩石分层和地形对地应力的综合影响。第二项任务包括在单轴、三轴和真三轴条件下测试各种各向异性岩石，以确定它们的弹性性质范围。第三项任务是进行膨胀仪试验，以确定野外各向异性岩体的变形特性。
