Abstract

Abstract: The anomaly verification reports of deformation from 2013 to 2020 were collected. The observation failures in these reports were statistically analyzed and classified. The failures can be divided into 7 categories, including instrument main failure, power supply and signal line failure, data collector failure, preamplifier and scale value failure, calibration system failure, coupled problem, instrument pier problem, respectively. Among them, the main problems are instrument main failure, power supply and signal line failure and scale value failure. This paper exhibits detailed examples about various observation system types, analyzes data variations caused by kinds of observation system failures, and suggests solutions.

Key words: Deformation observation, Anomaly verfication, Observation system failure, Calibration, Scale value
