Abstract Aiming at the problem of the small samples whose distribution is unknown,a novel method using the grey envelope to detect the gross error in deformation monitoring data is proposed.Firstly, according to the uncertainty theory of grey system, the grey envelope for gross error detection is established,and then the principle and its steps for gross error detection are introduced.Using the method to detect the deformation in underground building of a hydropower station, we finally draw a conclusion that the proposed method is feasible and effective.
Key words ：
