PILE DESIGN
Dutch Foundation Dubai design engineers follow a performance-based design approach that provides the most cost-effective foundation system whilst fulfilling project requirements. Our team is equipped with all necessary abilities, knowledge, and years of design and hands-on experience, all integrated to reduce efficient, high-performance deep foundation solutions at a minimized cost.
Dutch Foundation Dubai designers implement the most commonly used theoretical design techniques and powerful software. However, our strategic design methodology relies on our decades of experience and extensive geotechnical knowledge in our areas of the operation to complement theoretical findings and produce an optimized design in terms of safety, efficiency, performance, and cost.
Depending on the structure they are carrying, piles can be subject to axial (tension/compression), lateral loads, or a combination of any or all loads. Some of the sources for much loads are:
- The weight of the supported structure
- Earth and water pressures on retaining wall systems
- Wind loads
- Eccentric vertical loads
- Loads from waves and currents for offshore structures
- Slope movements
Piles are arranged in a number of ways so that they can support the load imposed on them. Vertical pile design are designed to carry vertical (compressive and uplift or tension) loads as well as lateral loads. Vertical piles are sometimes combined with raked piles to support lateral and vertical forces.
The pile design foundation entails ensuring that the pile type, size, depth, and number are sufficient to support the superstructure load without excessive settlement or bearing capacity failure. Deep foundations are more costly and difficult to construct than shallow foundations.
In the following cases, a pile design foundation can be used:
- When the upper soil layers are highly compressible and unable to maintain the load transmitted by the superstructure, piles are used to transfer the weight to bedrock or a stronger soil layer. When bedrock is not encountered at a sufficient depth under the ground surface, piles are utilized to gradually transfer the structural load to the soil. The frictional resistance created at the soil–pile interface is primarily responsible for the resistance to the applied structural load.
- When pile design foundations are subjected to horizontal forces, they bend while still supporting the vertical load imparted by the superstructure. This situation happens in the design and construction of earth-retaining structures and the foundations of tall structures subjected to strong wind and/or earthquake forces.
- The soils at the proposed structure’s site are often expansive and collapsible. These soils can go down to a large depth beneath the surface. Expansive soils swell and shrink when moisture content increases or decreases, and the resulting swelling pressure can be considerable. The structure may be severely impacted if shallow foundations are chosen.
- Transmission towers, offshore platforms, and basement mats below the water table all have foundations that are subjected to uplifting forces. To resist the uplifting force, piles are sometimes used for foundations.
- Bridge abutments and piers are usually built over pile design foundations to prevent a shallow foundation avoid losing bearing capacity due to soil erosion at the ground surface.
The process of pile desin foundations generally involves a thorough understanding of geotechnical site data, modeling, and analysis of the superstructure using FEA software, generation of support reactions, foundation design checks, and optimization in order to come up at a safe and cost-effective design.
