APPLICATION OF FUZZY INFERENCE IN THE ASSESSMENT OF SEA-ICE DAMAGE TO ENGINEERING STRUCTURE
The piling up of sea-ice in front of structure and its damage relate to many factors such as amount of sea-ice, thickness of ice floe, drifting speed of ice, velocity and direction of wind as well as height of the protecting wall of structure. Whether an ice floe can move cross the protection wall to damage the facilities depends on its size, thickness and velocity, etc. Due to changes of drift ice, complexity of ice floes distribution as well as different mechanisms by which sea ice damages various structures, it is difficult to build an accurate mathematical model to describe the process. However, after an analysis on the materials from practical investigations and experiments, and a study on the basic mechanics principles involved in the process, we can build a few proper fuzzy inference rules in order to assess extent of damage caused by sea ice. Here, we present the detailed steps to build a fuzzy inference system for evaluating drift ice damage on engineering structure, in which it is important to get a genuine understanding of structure form and characteristics of sea area where the structure locates. In addition, an application example is given with the purpose of examining the feasibility and validity of the approach provided in this paper.
