Drivability

Drivability analysis assesses the feasibility of installing driven piles by simulating the interaction between the hammer, pile, and soil. It predicts driving stresses, blow counts per unit penetration, risk of pile refusal, and overall driving efficiency. This helps optimize equipment selection and reduce the risk of pile damage or installation failure.

Pile Data:

Type, dimensions, and material properties

Pile splicing and section variations

Hammer Data:

Hammer type, energy rating, and efficiency

Cushion properties (pile cushion & hammer cushion)

Soil Data:

Soil layering and classification

Unit weight, shear strength, and friction/adhesion parameters

Soil resistance to driving (SRD)

Procedure for Conducting Drivability Analysis

Define Pile Properties:

Pile Type (Steel, Concrete, Timber, Composite)

Pile Dimensions (Diameter, Wall Thickness, Length)

Pile Material Properties (Elastic Modulus, Density, Yield Strength)

Pile Sections & Splicing (if applicable)

Define Hammer & Driving Equipment

Hammer Type (Impact, Diesel, Hydraulic, Vibratory)

Hammer Energy Rating (e.g., kJ or ft-lbs)

Hammer Efficiency & Ram Weight

Cushion & Cap Block Properties (Material & Thickness)

Define Soil Profile & Properties

Soil Layering (Stratification along pile depth)

Soil Type for Each Layer (Clay, Sand, Rock, etc.)

Soil Strength Parameters:

Unit Weight (kN/m³ or lb/ft³)

Shear Strength (Undrained & Drained)

Soil Resistance to Driving (SRD) (Static & Dynamic)

Friction Angle & Adhesion (for clayey soils)

Perform Simulation Using Drivability Software

Software like GRLWEAP (by Pile Dynamics, Inc. (PDI)) is used to model hammer-pile-soil interaction.

The software simulates blow count per depth, pile stresses, and driving resistance based on input data.

Multiple cases (e.g., different hammers, pile setups, or soil conditions) can be tested for optimization.

Analyze Results & Adjust Parameters if Needed

Blow Count vs. Depth Curve (Verifies drivability within acceptable installation limits)

Pile Stresses (Checks for potential overstressing or damage)

Refusal Risk Assessment (Predicts possible refusal depths & driving termination criteria)

Optimization of Hammer Selection & Pile Length (Ensures efficient and cost-effective installation)

Benefits of Drivability Analysis Before Piling

Prevents pile refusal & driving failures

Ensures piles can be installed within stress limits

Optimizes hammer selection for cost-effective driving

Minimizes pile damage & unexpected delays

Improves overall construction efficiency
