Frost heave
The deformation of the ground surface that is produced by frost heave has motivated almost a century of concerted laboratory, field and theoretical studies. Well before the development of equipment capable of resolving the microscopic films that support liquid transport towards growing ice lenses, early investigators predicted their occurrence and noted their importance. Idealized experiments c...
متن کاملExperimental Study of the Performance of Floating Breakwaters with Heave Motion
Nowadays, the application of floating breakwaters in small or recreational harbors has found more popularity. These types of breakwaters are more flexible in terms of design, configuration and especially installation compared with fixed breakwaters. In the current study, the performance of floating breakwater (FBs) under regular waves was studied using the physical modeling method. For the mode...
متن کاملAdaptive Heave Compensation via Dynamic Neural Networks
This paper discusses the problem of Adaptive heave compensation. A new estimator based on dynamic recurrent neural networks is applied to this problem. It is shown that the new algorithm is well suited for online implementation and has excellent performance. Computational results via extensive simulations are provided to illustrate the effectiveness of the algorithm. A comparative evaluation wi...
متن کاملFrost Heave in Colloidal Soils
We develop a mathematical model of frost heave in colloidal soils. The theory accounts for heave and consolidation, while not requiring a frozen fringe assumption. Two solidification regimes occur: a compaction regime in which the soil consolidates to accommodate the ice lenses, and a heave regime during which liquid is sucked into the consolidated soil from an external reservoir, and the added...
متن کاملImprovement of the heave motion of a semi-submersible platform with damping sheets subjected to sea waves
In this study, the damping sheets were attached to a semi-submersible platform to mitigate the heave motions. We first examined a typical GVA4000 semi-sub under a monochromatic linear wave train in deep water. an analytical method based on diffraction theory was used to determine the heave motion response. The results revealed that the analytical results show good agreement with available exper...
