| Abstract: | We take some different coupling materials to carry out an experimental research on the effects of different coupling materials between the snode and borehole using the hole-shaped strain apparatus.Through the experiments,we can see that the observations with the different coupling materials were different even we are using the same snode.The best results are to insert a metal rod as a composite of quartz sand in the coupling body,it has the advantage that the shortest time we need is just an hour from install the snode till perfectly record the solid tide,and the instrument zero drift is small.These data has a positive significance to explore what kind of coupling material we should use and how to carry out the earthquake emergency observations. |
