【摘要】 简要讨论了国内外钻孔应变观测技术近10年来的发展动态,分析了美、日技术的特点,然后,介绍了作者依据自身的技术积累,研制新型深井综合观测系统取得的进展。所研制的RZB型深井地壳形变宽频带综合观测系统采用数字化电容式位移传感器,具有噪声低、动态范围大的特点;基于井下数据总线技术,使得按不同要求进行观测系统集成非常灵活;通过完善井下探头安装工艺,提高了深井安装的质量。最后,对北京百善和福建漳州两个深井地壳形变综合观测实验站的建设及观测数据进行了讨论。更多还原

【Abstract】 The paper discusses briefly the development in borehole strain observation technology abroad and at home in the past ten years,and gives an analysis on the characteristics of implementing research projects in the United States and Japan.Based on technical foundations which the authors laid in the years past,the progress in new deep borehole multi-component observation system is then presented.With digital capacitance displacement transducer and downhole data bus,the RZB broadband multi-component observation system for crustal deformation measurement is characterized by low noise,large dynamic range and assemblage flexibility of various monitoring instruments,as well as high quality of deep borehole instrument setting due to improvement in installation technics.Finally the construction and observation data of two experimental observatories for crustal deformation,namely Baishan Station in Beijing and Zhangzhou Station in Fujian province,are discussed.更多还原
