LPILE v2015

LPILE v2015 by Ensoft, Inc. is a geotechnical analysis program for evaluating the lateral response of single piles and drilled shafts. It models nonlinear soil–structure interaction with established p–y curve methods and supports multilayered soil profiles, groundwater conditions, and a range of pile materials and shapes. Engineers use LPILE to estimate pile deflection, bending moment, shear, and soil reaction with depth, and to develop pile-head load–deflection relationships for design and verification. The software is widely applied to bridge, marine, and energy projects where lateral demands from wind, waves, current, impact, or seismic loading govern foundation performance.

Key capabilities:

• Nonlinear p–y analysis with built-in models for sands, clays, and weak rock, plus options for user-defined curves and modifiers
• Support for static and cyclic loading
• Layered soil profiles with depth-varying properties and groundwater levels
• Broad section and material options (e.g., steel, concrete, timber; H-piles, pipe piles, drilled shafts), including nonlinear section behavior for reinforced concrete
• Flexible pile-head boundary conditions (free, fixed, or user-specified translational/rotational springs)
• Application of lateral loads and moments at the head and distributed loads along the shaft
• Clear graphical and tabular outputs of deflection, moment, shear, soil reaction, and p–y response
• Tools for running and comparing multiple load cases and generating concise design reports

Typical uses:

• Design and assessment of bridge foundations, piers, and abutments
• Marine and waterfront structures such as wharves, dolphins, and jetty piles
• Energy and utility structures, including transmission line and sign foundations
• Serviceability checks, capacity evaluations, and retrofit or remediation studies
