Cyclic friction tests between laboratory grown columnar ice and micro-concrete plates were performed at –10°C to study ice–concrete friction under conditions similar to those observed in ice–structure interactions. This paper presents the results obtained in terms of friction coefficients. Effects of time and contact conditions are analysed, and conclusions about the effective physical mechanisms of friction are drawn. These conclusions are validated by a simple model of the ice–concrete contact.Key words: ice, structure, concrete, contact, interaction, friction, law, model, viscoplasticity, roughness.

Working Principle

The paper introduces the working principle of a logging instrument, and according to the working principle and instrument’s function of two-way hydraulic control valve. Facing to the key problems of process equipment in the actual service and workflow, the structure of value was designed and optimized. At the same time, the logging instrument with a dual-channel and two-way hydraulic control valve is designed and processed. Meanwhile, we build an experimental platform and make the experiment according to principle of the instrument. The results show that the design of this dual-channel and two-way hydraulic control valve logging instrument met the work requirements, and it has high reliability in oil exploration, which could be promoted and used in logging areas.
