Evolution Patterns of Frost-Heaving Pressure with Partial Ponding in Cold Region Tunnels
The calculation of the frost-heaving pressure is one of the key issues in the frost-resistant design of tunnels in cold regions. To reveal the frost heave mechanism of partial ponding behind the tunnel linings, a three-dimensional geo-mechanical model ...

Heave motion suppression of a Spar with a heave plate [PDF]
Abstract Vortex shedding flow of an oscillating vertical cylinder with a disk attached at its keel is considered. This configuration is of interest for the offshore oil and gas industry. A finite difference method is employed to solve the incompressible Navier–Stokes equations in the primitive-variables formulation.

Measurement of Suction Pressure Generated in the Process of Frost Heaving in Rock
Recently it has been found that frost heave phenomena can be seen not also in soil but also in rock. It is obvious, however, that the number of researches on frost heaving in rock is much less than that of researches on frost heaving in soil.
