approach, the bearing capacity is estimated using the static bearing capacity factors and any effects of the earthquake loads on the supporting soil are not considered. This implies that the failure surface below the foundation for the earthquake load is assumed to be the same as for the static case.

The allowable bearing capacity (q a) is the maximum bearing stress that can be applied to the foundation such that it is safe against instability due to shear failure and the maximum tolerable settlement is not exceeded. The allowable bearing capacity is normally calculated from the ultimate bearing capacity using a factor of safety (F s).

The bearing capacity for granite, limestone, and sandstone was found to be approximately four to six times the unconfined compressive strength of the rock material when the load was applied perpendicular to the rock surface.

GasBearing Capacity of Rock. the amount of free or retained gas (primarily methane) contained in a unit of mass or of volume of rock under natural conditions, measured in cu m per ton or cu m per cu m. Coal deposits have the highest gasbearing capacity. For example, at atmospheric pressure, 1 cu cm of coal has the capacity to retain 78 cu cm...

Bearing capacity is the measurement of the soil pressure a soil can safely bear. In other words, bearing capacity is the pressure which soil can withstand before it fails. The two most important soil failure criteria are: Shear failure; Maximum allowable settlement; Among many factors, foundation width (B) can influence failure criteria.

Test data obtained in several investigations of the relation between ultimate bearing capacity and the ratio of footing area to loaded area of concrete and rock foundations are summarized. The results show that for the higher ratios (over lO:l), the AC1 Code requirements are too conservative.

Oct 21, 2005· Rock Allowable Bearing Capacity 3. An old way we used to do for rock was simply drill auger borings, and categorize the drilling as easy, medium, medium hard, hard, and very hard. Medium hard to very hard was given 3000 psf without SPT for simple one and two story structures, but the questionable drilling was checked with SPT.

a. Bearing Capacity. Bearing capacity is the ability of soil to safely carry the pressure placed on the soil from any engineered structure without undergoing a shear failure with accompanying large settlements. Applying a bearing pressure which is safe with respect to failure does not ensure that settlement of the

Plate Load Test is a field test for determining the ultimate bearing capacity of soil and the likely settlement under a given load. The Plate Load Test basically consists of loading a steel plate placed at the foundation level and recording the settlements corresponding to each load increment.
