Evaluation of Spatial Characteristics of Corroded Situations in Service Steel Sheet Piles by Applying Geostatistics

The corrosion degradation of the steel sheet pile material accelerates in recent years. extremely accelerated induces thickness loss and decreases mechanical characteristics. It is essential to evaluate corroded situations for design maintenance infrastructures. In this study, spatial characteristics service canals were evaluated by geostatistics with variogram kriging. experimental procedures, thicknesses measured drainage canals. sampling was conducted air, tidal, water, sludge soil zones. analytical analysis modeling structures distribution. ordinary kriging based on theoretical interpolates no-sampling area. As a result, profile shows largest tidal zone. interpolation acceleration flanges
