Pile Group Analysis, Laterally Loaded Piles, P-Y Curves and Rock Socket.

Innovative Geotechnics is an engineering company with the aim of researching and developing geotechnical design and analysis programs. 

Innovative Geotechnics provides innovative geotechnical design tools for soil-structure interaction and deep foundation problems such as single piles or pile groups under lateral and vertical loads. 

Single Piles and Pile Groups

Innovative Geotechnics provide geotechnical design tools for soil-structure interaction problems such as pile groups, laterally loaded piles, nonlinear p-y curve generation, and rock socket design, including single piles or pile groups under lateral and vertical loading based on finite element method. Our programs are focused on the geotechnical analytical knowledge, improving user engagement, and reducing potential input uncertainties. All geotechnical programs and software adopt simple input interfaces for the users to interactively enter the analysis information such as soil layer information, soil properties, and foundation design parameters. 

Key Features of Deep Foundation Design Programs

Nonlinear behavior of soils and rocks for pile foundations under axial and lateral loading

• Finite element method based on Garlerkin formulation instead of lumped springs at the element node like the conventional finite difference method;

• Powerful nonlinear solver based on the arc-length approach;

• Nonlinear bending stiffness of piles;

• Both static and cyclic behavior of soils for laterally loaded piles based on p-y curves;

• Displacement loading for piles subject to soil movement based on the approach of Byrne et al. (1984); and

Efficient and powerful visualisation of analysis results through well-designed graphics outputs

• Plotting nonlinear p-y and t-z curves for any location along the pile length;

• Plotting deflection, bending moment, shear force, soil reaction, shaft and end bearing resistances and many other results;

• Displaying pile load and settlement curve at the pile head for axial and lateral loading;

• 2D and 3D graphics outputs for the pile group analysis results; and
