Measurement Test of the Friction Factor between Leveling Propulsion Resistance and Steel Leg Footing Plate

For accomplish the research topic of key technology for leveling prepared rubble base in offshore deepwater port,the dedicated test units were designed and produced,the measurements of the propulsion resistant force has been taken to rubble spreading unit of leveling device and the friction factor between steel footing plate and rubble bed,the test results were summarized in order to provide data for the design of leveling device.
