Such soil is referred to as "frost heave susceptible.
Visible vertical displacement of the ground surface or effects on pavement would be consistent with the occurrence of frost heave.
The primary structural integrity effect to pipeline systems as a result of frost heave is excessive longitudinal or bending stress due to the displacement strain imposed by the earth movement.
Silty and loamy types of soils may be susceptible to frost heave while clay, clean sand and gravel are not.
When only a few stones--about 100 per square meter--were scattered across the pair's cybertundra, frost heave
shaped them into small heaps.
In 1989, Dash proposed that modest temperature differences can drive flows in these liquid surface films and contribute to frost heave
The new equations apply to any pure, frozen substance and thus appear to rule out the notion that frost heave results from water's unusual habit of expanding as it freezes, Dash says.
Since the calculations indicate that frost heave produces more thrust when it occurs in coarser substances, Hallet suggests using finer-grained concrete to build heave-resistant foundations.
On a local level, Wolff wants to help bring Vermont into the 21st century with the Frost Heaves - the name comes from a common term in the region that describes what happens when the moist ground freezes so fast that it juts up and brings traffic to a crawl.
Eventually, Wolff wants ownership of the Frost Heaves to filter into a community trust, and he plans to take advantage of the local businesses (Ben and Jerry's, for one) on the concessions.
As with the human counterpart diseases, the airways of horses afflicted with heaves become clogged with mucus or damaged by scars, and inadequate blood oxygenation depletes them of their energy.
In addition to its product for equine heaves, the company has developed therapeutics for feline leukemia, canine mast cell tumors and cardiomyopathy.
