Selection of Pile Foundation Based on Soil Condition
The selection of pile foundation depends on the soil investigation data received from soil exploration bore holes at different depths. Selection of appropriate pile for the desired strength and requirement plays an important role in cost reduction and efficiency. In ...
Calculate Capacity of Pile Group and Efficiency
Capacity of pile group is the sum of the individual capacities of piles, but it is influenced by the spacing between the piles. Piles are driven generally in groups in regular pattern to support the structural loads. The structural load ...
What are the Needs and Functions of Pile Foundation?
When it becomes impossible to provide the suitable surface foundation for a structure; the use of pile foundations becomes necessary, this situation arose from either the soil condition or the order of bottom layers, the nature of the loads transferred ...
How to Determine Depth of Foundation?
Many factors affects the depth of foundation. such as type of soil, ground water table, loads from structure, bearing capacity and density of soil and other factors. The minimum depth of foundation is calculated by Rankine’s formula when the bearing ...
Pile Load Capacity Calculation for Single Pile and Group Piles
The Pile load capacity calculation will determine the ultimate load the pile foundation can take under service load condition. This capacity is also called as bearing capacity of piles. The piles installed can be a single pile or group piles. ...
Structural Defects of Foundations at Construction Stage
Structural defects occur in foundations at construction stage. There can be many causes for these defects. The problem areas, effects in foundation and defects in structure due to those causes are presented here.
Load Test on Piles – Methods of Pile Load Test
Load tests on piles are conducted on completion of 28 days after casting of piles. Two types of tests namely initial and routine tests, for each type of loading viz. vertical, horizontal (lateral) pull out, are performed on piles. Initial ...
