Small Scale Model Tests of Ice Gouge in Soft Sandy Silt

Small scale gouge tests were designed and executed at the University of Stavanger in Norway as a part of master thesis work. A box (2.5 × 2.5 m) was filled with soft sandy silt and several gouge tests were performed. The subgouge soil deformations, the soil mound dimensions and the ratio between initial and residual gouge depth were measured under varying gouge parameters. Vaneshear and T-bar tests were used to estimate soil properties. A pipe segment was buried under the gouge and strains in the pipe were monitored in some of the tests. Test results are presented in this paper, including FE simulations of some of the performed experiments.

AbstractBased on the response of small-scale model square footing, the present paper shows the results of an experimental bearing capacity of eccentrically loaded square footing, near a slope sand bed. To reach this aim, a steel model square footing of (150 mm × 150 mm) and a varied sand relative density of 30%, 50% and 70% are used. The bearing capacity-settlement relationship of footing located at the edge of a slope and the effect of various parameters such as eccentricity (e) and dimensions report (b/B) were studied. Test results indicate that ultimate bearing capacity decreases with increasing load eccentricity to the core boundary of footing and that as far as the footing is distant from the crest, the bearing capacity increases. Furthermore, the results also prove that there is a clear proportional relation between relative densities –bearing capacity. The model test provides qualitative information on parameters influencing the bearing capacity of square footing. These tests can be used to check the bearing capacity estimated by the conventional methods.

It is suggested that reinforced ice domes in spans up to 100–150 metres and constructed by spraying water onto a spherical inflatable membrane could be economic solutions for constructing temporary enclosures in cold regions. The feasibility and practicability of such a novel and economical erection/construction technique has been demonstrated at The University of Calgary by constructing small-scale model ice domes and testing them until failure. Details of this erection technique, properties of the reinforcement (spun fibreglass yarn) and the load-deflection-time behaviour of the model domes are described. The first part of the paper gives some results on the short-duration load and creep response of unreinforced and reinforced ice samples, including shear. pull-out/bond and tensile strength. The results indicate that such fibreglass yarn reinforcement does not enhance the shear strength of ice but does inhibit initiation and propagation of cracking and thereby increase the ultimate tensile strength of the composite.

Wave energy is a renewable and non-polluting source and its use is being studied in different countries. The paper presents an overview on the harnessing of energy from waves and the activities associated with setting up a plant for extracting energy from waves in Port of Pecem, on the coast of Ceara State, Brazil. The technology employed is based on storing water under pressure in a hyperbaric chamber, from which a controlled jet of water drives a standard turbine. The wave resource at the proposed location is presented in terms of statistics data obtained from previous monitoring. The device components are described and small scale model tested under regular waves representatives of the installation region. Based on the experimental results values of prescribed pressures are identified in order to optimize the power generation.
