Influence of inclinometer basement and analysis of the zero drift
摘要
Abstract
Through distinction ananlysis against a life cycle observation data which we got from the three inclinometers in the deformation cave of the Changshu Seismic Station, we can find the basement influence and reasons which caused longterms zero drift. And then we can provide the method for the segregation of quantitatively determine and improve the procedure of instrument installatin. Analysis stated that sustained loading of base stone block will produce creep of concrete. The creeping against different thickness of the concrete will lead to base stone block tilt. The process is non-linear. It shows the development of exponentially distributed and run through the life cycle of the instrument.关键词
