초록

In this study, quartile control chart method is tried to apply to determine limit values of existing dams of K-water’s instrumentation data for dam safety, show asymmetric distributed data, and the example of application is presented. The determined limit values of concrete stress meter and concrete non-stress meter by Shewhart method and quartile method show that the determined limit values by Shewhart method indicate that the majority of instrumentation are on abnormal condition, although the measured values are normal behavior. But, in case of the result of quartile method has such an error. Like this, it is judged that the determination of the limit values of dam instrumentation, show asymmetric and abnormal distributed data, by the quartile method is appropriate. Therefor The quartile method is applied to the determination of limit values of existing dam instrumentation of K-water.
