Abstract
The drilling strain observation techniques have been played a very important role in the research field of geodynamics and earthquake prediction, and have been gotten wide applications. We have achieved a number of observational solid tide data from the station without the influence and interference from ground. The apparatus could record clear and stable solid tide and strain wave with coseism. Through the solid tide model of Nakai, we calculated and gained solid tide proportion factors in the directions of deepwell, from deepwell strain observation, to verify that the tide response to the theoretical tidal factor model in Baishan station is a very large dispersion and a regular azimuthal anisotropy. The high precision deepwell solid tide observation and tidal response anisotropy phenomenon is expected to be on the dynamics, earthquake prediction, to provide a reference to improve the tide displacements of observation data in space geodesy.
