The only way to specifically calculate the load capacity of concrete is to have a licensed structural engineer process the formulas and consult a myriad of tables that all apply to the specific design of your project. You can, however, calculate the load capacity of concrete in a quick and general way.
Concrete fords. Use a concrete ford crossing only where the foundation of the stream crossing has adequate bearing strength. Perform a subsurface investigation that is in sufficient detail and analysis to support the design. Describe the soil material observed, subgrade conditions, bearing capacity, and depth to bedrock.
Bedrock subgrades, if encountered, should not be steeper than 4 Horizontal to 1 Vertical (4H:1V). Low spots in the bedrock subgrade may be filled with lean concrete or ¾-inch crushed stone to provide a reasonably level surface. Bedrock subgrades do not require proof rolling.

Types. To install a caisson in place, it is brought down through soft mud until a suitable foundation material is encountered. While bedrock is preferred, a stable, hard mud is sometimes used when bedrock is too deep. The four main types of caisson are box caisson, open caisson, pneumatic caisson and monolithic caisson.. Box. A box caisson is a prefabricated concrete box (with sides and a ...

Micropiles (minipiles) are an economical alternative to large diameter drilled shaft foundations, especially in difficult ground conditions, karst geology, or restricted access situations. They may be reinforced with a threaded bar (75K) to attain the correct design load capacity. Micropiles are often preferable to "H" piles because of ...
from high-capacity wells may represent average ground-water quality for a large cone of influence (Sasman and oth-ers, 1981). Also, because much of the bedrock in the southern part of the basin does not produce much ground water, it is not uncommon for bedrock wells to be deep and to intersect several different bedrock units.
May 29, 2020· The bedrock layer was made by mixture of cement, brick and ceramic (in the proportion of 20%, 45% and 35%, respectively) to obtain the strength characteristics mentioned in Table 1. To obtain such an equivalent rock, direct shear laboratory test was performed on four different samples.

of concrete piles were devised. These early concrete piles were the cast-in-place type. Further development of the concrete pile led to the precast pile and, relatively recently, to the prestressed concrete pile. The need for extremely long piles with high bearing capacity led to the use of concrete-filled steel-pipe piles about 50 to 60 years ago.
