InfraGEO Software provides geotechnical and seismic engineers with cost-efficient and time-saving but state-of-the art geotechnical analysis tools developed in very easy to use macro-enabled EXCEL applications to solve their challenging seismic and foundation design/analysis projects.

SITE CHARACTERIZATION AND SEISMIC ANALYSIS

SPTPROP performs site characterization using standard penetration test (SPT) data and evaluates site class (soil profile type) used in seismic design and estimates commonly used geotechnical design parameters such as friction angle of granular soils, undrained shear strength of cohesive soils, Poisson's ratio, Young's modulus of elasticity, shear modulus, and bulk modulus.

SPTLIQ analyzes liquefaction hazards at a site, including estimation of liquefaction severity, seismically induced settlements, cyclic and permanent lateral displacements, using standard penetration test (SPT) data following the liquefaction triggering methods by NCEER/NSF by Youd et. al. (2001), Cetin and Seed (2003), and Boulanger and Idriss (2008, 2014).

LATSPREAD estimates the magnitude of anticipated liquefaction-Induced lateral spreading based on the empirical methods proposed by Youd, Hansen, and Bartlett (1999) and Bardet, Mace, and Tobita (1999) for a user-specified design earthquake.

SLOPEDISP computes the amount of Newmark-type slope displacements as a function of seismic yield acceleration and earthquake magnitude using three methods of analysis proposed by Ambraseys and Menu (1988), Bray and Travasarou (2007), and Jibson (2007).

DEEP FOUNDATION ANALYSIS & DESIGN

AXIALCAP calculates the axial capacity and settlement of large or small-displacement driven piles and drilled shafts, based on pile capacity formulas using NAVFAC (1986) and FHWA (Reese and O'Neil, 1988) methods. It works with either Allowable Stress Design (ASD) or Load Resistance Factor Design (LRFD) methods.

PILEPY evaluates the lateral soil resistance versus deflection (p-y) curves used for lateral loading analysis of a single pile founded on layered soils.

SDPILE computes the axial and lateral capacities of a short drilled pile foundation.

SHALLOW FOUNDATION ANALYSIS & DESIGN

FTGCAP analyzes the bearing capacity of a spread footing using the formulas recommended by Terzaghi (1934), Meyerhof (1963), Hansen (1970), and Vesic (1973). It works with either Allowable Stress Design (ASD) or Load Resistance Factor Design (LRFD) methods.

FTGSETT estimates the settlement of elastic and consolidation settlements of a spread footing using laboratory and field test data.

FTGSTIFF calculates the dynamic stiffness parameters or spring constants of a spread footing used to analyze translational, rotational, and torsional movements of a shallow spread foundation based on the formulas derived by Gazetas (1991).

EMBANKMENT SETTLEMENT ANALYSIS

EMBANKSETT estimates the elastic and consolidation settlements due to placement of a long, infinite, trapezoidal fill embankment on the ground using laboratory and field test data.

SLOPE STABILITY ANALYSIS

SLOTCUT analyzes the 3-D stability of a temporary vertical cut slope.

RETAINING WALL ANALYSIS & DESIGN

EPRESS analyzes the static and seismic lateral earth pressures used in design of flexible or rigid retaining walls. It works with either Allowable Stress Design (ASD) or Load Resistance Factor Design (LRFD) methods.

MSEWALL evaluates the external stability of a mechanically-stabilized earth (MSE) walls based on recommended procedures by the Federal Highway Administration (FHWA, 2001).

ABUTSTIFF evaluates the ultimate passive resistance, stiffness, and force-deflection curve of a bridge abutment wall.

WALLPY evaluates the lateral soil resistance versus deflection (p-y) curves used for lateral loading analysis of a retaining wall on layered soils.
