摘要
在安装福州地震台TJ-2型体积式应变仪过程中,发现存在钻孔选点与观测室分开考虑等问题,提出一些建议。井孔注水试验结果揭示,该井孔探头顶部可能存在一个与探头近距离的含水层干扰。初步对气压、水位、降雨影响进行分析。
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.
