METHODS FOR MEASURING THE DEPTH OF ICE ABRASIA ON THE SURFACE OF CONCRETE SAMPLES

Abstract

The shelf of the world ocean is rich in hydrocarbon reserves. Most of the Russian shelf is located in the Arctic and Far Eastern seas, where the harsh climatic conditions of the construction areas must be taken into account when designing offshore ice-resistant platforms, cargo terminals and ports, and designers must pay special attention to the loads and impacts from the drifting ice cover. The result of the interaction of drifting ice fields with hydraulic structures is the abrasive wear of the structure surface (concrete). The problem of ice abrasion of building materials attracts the attention of scientists in many countries. As part of the study of this phenomenon, many experiments are conducted, where the method of measuring the ice abrasion depth may bring a significant error in the results of the experiment, which contributes to the need to apply new measurement methods and improve existing ones. For example, at the Norwegian University of Natural and Technical Sciences, Mitutoyo Corp. digital micrometer, 3D optical light scanner ATOS III SO and laser scanner processing were used throughout the experimental studies. At the Far Eastern Federal University, measurements were carried out using a micrometer watch type indicator (WTI) GOST 577-68 (2002) and a digital micrometer. The article describes the methods of measuring the ice abrasion depth and gives the characteristics of measuring equipment, a method for measuring the of ice abrasion depth with numerical control equipment is proposed.
