To sum up, the combination of some factors and levels of coarse-grained soil also produces certain frost heave. The factors affecting the frost heave of coarse-grained soil include the following aspects: the gradation of soil particles, the content of fine particles and their mineral composition, water content, density, permeability coefficient, capillary action, and external load [35-37].
Accordingly, this kind of regional climatic condition is apt to intensify moisture migration and frost heave. All soil samples were collected from the field experiment section at Qinghai Guoluo Airport.
For example, in the 1990s, an adaptive filter algorithm for heave motion was developed by Godhavn and was implanted in the seatex MRU .
In order to get accurate heave motion which is based on strapdown inertial navigation system (SINS) composed of inertial sensors with high accuracy, it is necessary to select a sea model which can better reflect the actual situation to analysis.
results from ice forming beneath the surface of soil during freezing conditions in the atmosphere.
As impressive as frost heave
can be, as far as buildings go, who cares about how high frost heave
can go if the direction of heave
are most common in poorly drained soil, so first try regrading around the exterior to keep rainwater away from the slab.
When only a few stones--about 100 per square meter--were scattered across the pair's cybertundra, frost heave
shaped them into small heaps.
That's because these connected structures will damage the house if they heave
. This may seem like a pain if you're adding a deck or front porch, but porch floors can heave
up under doors, and tilting decks can pull house walls outward.
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.
He said that the troops also set ablaze four hundred wooden apple boxes and heaves
of animal fodder.
ISLAMABAD -- The family members of a martyred youth, Sameer Ahmed Butt, have said that Indian troops torched their house and heaves
of fodder and four hundred apple boxes in Drabgam area of Pulwama district.
