怀来形变观测山洞密封保温改造对摆式倾斜仪观测的影响OA

Since the sealing and thermal insulation renovation of the Huailai deformation observation cave was completed in 2018,the quality of observation data from the vertical pendulum and horizontal pendulum tiltmeters installed in the cave has steadily improved,earning numerous awards in national evaluations of similar observation datasets.This paper briefly describes the renovation measures implemented for the cave,comparatively analyzes the effects of environmental factors such as cave humidity and meteorological conditions on observation quality before and after the renovation,and evaluates the quality and accuracy of the observation data.The results demonstrate that the overall thermal insulation renovation has achieved remarkable moisture-proofing,optimized the observation environment,and reduced disturbances from meteorological factors such as strong winds and air pressure,thus effectively improving the observation accuracy of pendulum-type instruments.The renovation project for the deformation observation cave at Huailai Seismic Station has been proven successful,and its experience can serve as a valuable reference for other seismic stations.
