| Abstract: | Problems appeared in the installing Tj-2tpye volume strain meter in Fuzhou seismic station,that where drill the hole and where to be the observing room were considered at different time and so on,are discussed and some suggestions are given.The results of the drill-hole water injection test in Fuzhou seismic station indicated that the thickness of the cement layer on the top of sensor did not reach design request and there is the disturbance of aquifer layer in the segment of the drill-hole to the strain-meter observation.The influence of atmospheric pressure and water level and rainfall to the volume strain is analyzed. |
