The use of multiple geotechnical programs creates the need to learn the unique interface of each program. Even more inefficiencies arise when there is a need to perform various analyses for the same project. For example, dam and levee projects often require seepage, settlement, slope stability, and seismic analyses to be calculated. The same also applies to foundation and retaining wall projects that require soil structure interaction as well as stress deformation analyses to be performed. Most geotechnical programs can only perform one analysis type, which creates the need to tediously create the same project model for several programs. With GTS NX you will no longer need to rely on several different geotechnical programs to perform various analyses. Instead you will be able to use GTS NX to perform any type of geotechnical analysis application .GTS NX can perform both single and group pile interaction as well as complex tunnel analysis in either 2D or 3D. Linear static analysis, seepage, soil structure interaction, SRM slope stability analysis and a wide range of dynamic analysis applications can be done as well. Moreover, your efficiency will be greatly increased by the ability to run multiple analysis types on a single model file.
Foundation AnalysisOverviewGTS NX handles the full range of foundation analyses. You will be able to perform thorough analyses of spread footings, deep foundations, pile foundations, and shaft foundations. The advanced post- processor will generate results that you can then use to determine horizontal pile foundation movement, bearing capacity, and differential settlements. The program also has the unique and advantageous ability to simulate group pile behavior. This ability will save significant amounts of time when determining the ultimate bearing capacity of group pile configurations. GTS NX has foundation analysis capabilities that also extend to the investigation of the effects of new foundations on existing structures. With GTS NX you will be fully able to study the settlement and decrease of stability of adjacent structures due to the additional loading caused by your project footing.

Staged ExcavationOverviewDeep excavation projects often require an analysis that accounts for the changes of the project site over each stage of the excavation. GTS NX enables you to analyze each stage of the excavation sequence along with the permanent and temporary structures that are to be constructed during each respective phase. A key advantage of the program is its ability to calculate highly accurate bending moments and deflections of retaining elements. You can use these high quality results to optimize your design while fully accounting for the maximum allowable bending moments and deflections of your retaining walls. GTS NX is equipped with advanced modeling and post processing features that have been designed to simplify and streamline the once time consuming and complex process of performing finite element analysis for excavation. Thus you can obtain in depth results with a minimal investment of time and effort.

Seepage AnalysisOverviewGTS NX has been used extensively by engineers to analyze the transient flow of homogenous and zoned embankments. One of the many key advantages that GTS NX has to offer for these applications is that it enables you to easily model very complex 2D or 3D geometry and layers of stratification. Another unique and important advantage made possible through GTS NX is enables you to accurately model zones in which seepage gradients or velocities are high by varying the size of the elements. Complex seepage project applications such as these can only be modeled with finite element software. With GTS NX you will be able to perform any type of complex seepage analysis investigation. These investigations include the study of pore pressure changes, the effects of precipitation and evaporation, and relief wall spacing.

Slope AnalysisOverview3D finite element analysis of slopes provides highly detailed results that are far more accurate than results obtained through conventional 2D limit equilibrium method analysis. However, the complexity and time-consuming nature of 3D finite element analysis has caused many engineers to prefer the limit equilibrium method. GTS NX has a user-friendly modeling interface that has been specifically designed to overcome these limitations. These functions will enable you to use the finite element method to analyze slopes with unmatched levels of ease, efficiency, and precision.

Dynamic AnalysisOverviewGTS NX will enable you to fully benefit from the use of 2D and 3D models for seismic analysis. One of the key advantages of using 2D and 3D models for seismic analysis is the ability to consider project complexities such as soil anisotropy, irregular soil stratigraphy, surface waves, irregular topography, and soil-structure interaction. Another key advantage of using 2D and 3D models is that seismically induced permanent displacements can be estimated. GTS NX is capable of performing response spectrum analysis for conventional projects as well as time history analysis for high-end seismic design calculations. For response spectrum analysis GTS NX uses the natural frequency to calculate peak values of seismically induced displacements, ground velocities and ground accelerations.

TunnelingOverviewGTS NX is fully equipped to model and analyze each phase of tunnel construction, including a simulation of the excavation itself and the installation of supports. Shield TBM analysis can be performed to obtain maximum axial forces, sheer forces, bending moments and radial displacements of the tunnel for each phase of the construction sequence. GTS NX also enables you perform analyses of various types of tunnel linings such as unsupported rock, shotcrete, and unreinforced concrete systems. You can also take multiple load cases into account such as vertical stresses in soil and horizontal pressures on the tunnel surface. Afterwards you can run the analysis to calculate the resulting forces and moments for each element of the lining.
