【摘要】 针对人为干扰对形变观测仪器的影响，结合会昌地震台观测环境，以DSQ型水管倾斜仪为例，在观测山洞内设计过道桥。通过应用波西涅斯克解，计算人员活动对仪器造成的干扰位移，分析干扰曲线变化特征，并据此确定过道桥最佳放置地点，旨在有效降低甚至消除人员活动对仪器的干扰，以提高观测数据完整率，提升观测资料质量。更多还原

【Abstract】 In response to the influence of human activities on deformation observation instruments,combined with the observation environment of Huichang Seismic Station, this study takes the DSQ type water-tube tiltmeter as an example and designs a crossing bridge in the observation cave.The interference displacement caused by human activities to the instrument is calculated using the Boussinesq solution. The variation characteristics of the interference are analyzed, and the optimal placement location of the overpass bridge is determined accordingly. The aim is to effectively reduce or even eliminate the interference of human activities on the instrument, so as to improve the completeness rate of observation data and enhance the quality of observation data.更多还原
