For horizontally isotropicsoil layers, resistivity changes due to stress variation exhibit directivity, that is, the changes measured along different profiles are not identical.
水平各向同性土层，在应力作用下，不同方向电阻率变化不同，呈现出方向性。

The corrosive cells formed in non-isotropicsoil are characterized by their intense corrosive nature, and so the like zone should be kept away as much as possible in survey and design.
异性土壤所形成的腐蚀电池，具有强烈腐蚀的特点，类似这种地带应在勘察设计时尽量避开，绕道而行。

The single pile is simplified to elastic shaft elements suffering skin friction and the soil mass is considered to be homogeneous isotropic elastic semi space.
