overburden pressure

At equivalent to the overburden pressures, the soils had of 6–8°.

The plots were made for different overburden pressures.

Overburden pressures are successfully simulated with a pressurized air bladder.

The deeper the well, the more overburden pressure, which means the greater the annular compressive stress conditions.

The fluid pressure is compared to the ice overburden pressure, p, given by ρgh.

Overburden pressure varies in different regions and formations.

A linear relationship between effective overburden pressure and the flow of water into or out of a freezing soil was observed.

The measured vertical pressure at the crown of the pipe in the field ranged from 0.24 to 0.36 times the overburden pressure.

A study to observe the effects of overburden pressure and other parameters on the freezing behavior of a saturated soil was undertaken.

The cracking failure pattern is suppressed by shearing for a clay liner with an increase in overburden pressure.

After deposition some or all of the lapilli can become flattened and/or elongated due to overburden pressure.

Compaction of the sediments under very high overburden pressure has caused appreciable porosity reduction.

Therefore, a lower overburden pressure is usually generated at an offshore depth, than would be found at the same depth on land.

The laboratory measurements of matric suction can be adjusted for the effect of overburden pressure in the field.

Furthermore, the discrete ice lens method predicts the effects of changing overburden pressure on the predicted heave rate.

Mathematically, overburden pressure can be derived as:

Dynamic penetration resistance normalized for effective overburden pressure appears to be the more sensitive indicator of changes in material density.

These include footing size, overburden pressure, footing material, soil disturbance, and soil properties.

The results indicate that the effect of overburden pressure and of footing material is less significant than that of the other variables.

Furthermore, a relatively good relationship is found between the in situ void ratio of Ariake clays and the effective overburden pressure.

Overburden pressure is the pressure exerted by the weight of the rocks and contained fluids above the zone of interest.

The model relates the physical properties of clays, such as its surface area, with the overburden pressure and the concentration of ions in the permeant.

The effect of overburden pressure on liquefaction resistance of sand is studied and results of a site-specific investigation are presented.

If the excess pore pressure generated exceeds the in-situ effective overburden pressure then liquefaction occurs.

With increase in overburden pressure, more stress is placed on the grain to grain contacts and compaction starts to proceed by chemical processes.
