| 摘 要： | 氢气动态与断裂活动、 地震的关系密切。 在川滇实验场范围内的安宁河断裂带和则木河断裂带选取典型场地, 建设由连续观测点和定期观测点组成的观测台阵, 开展连续高精度氢浓度、 同深度地温和环境气温、 气压同步观测, 进行氢气观测技术研究工作。 着重介绍高精度氢地震观测台阵的设计思路、 建设内容以及运行情况, 并分析了观测数据。 结果表明, 观测台阵建设的技术指标达到设计目标, 并讨论出了断裂带土壤氢气连续观测与定期观测点的建设方案与技术指标。 为期一年的连续观测数据显示, 氢气浓度背景呈现出“北高南低”的分布格局, 暗示了不同构造区氢气浓度的背景特征。 |

| Abstract: | Hydrogen gas released by chemical and mechanical changes in crustal rocks closely correlates with fault movement and seismic activities. Observation array,including continuous observation points and mobile observation points,is established in the Anninghe fault zone and Zemuhe fault zone of China Earthquake Science Experiment site to monitor hydrogen concentrations,geotemperature,air temperature and atomospheric pressure. The array also provides an opportunity for studying the high-precision hydrogen observation technology. We describe the design ideas,construction process and operation condition of the observation array and conduct a preliminary analysis of the observation data. The results show that the construction of the array attains the prearranged technical index. The construction scheme and the technical specifications for the hydrogen observation points are also discussed. Continuous monitoring data of one year shows that the hydrogen background value is remarkably high in the north region than the south,which indicating the background characteristics of hydrogen in different tectonic regions. |
