Excavations and
Open Pit

Excavations cover a wide range of geotechnical engineering from building construction to open pit mining. Deep 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.

Pile Foundation

GTS 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.

Tunneling and

GTS 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.

Slope Stability

3D 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.


In structures founded on non-rigid formations, the soil flexibility influences structural response and vice versa. This phenomenon is called Soil-Structure Interaction (SSI). SSI is one of several factors influencing response to seismic loads that include source effect, travel path effect and site-response effect. SSI is an important factor in many applications such as train-induced vibrations, vibration reduction measures for soil waves, machine foundation vibrations and seismically loaded structures, etc.

GTS NX can import model information such as mesh, material, structure cross section and load & boundary condition from MIDAS family software (Gen and Civil). After calculation, the ‘Export Nodal Results’ feature from GTS NX model to midas Gen/Civil allows for outputting the results of the reaction-displacement results calculated from the existing constraint locations as well as the force-displacement results of the nodes subjected to the nodal load.

Groundwater Flow

GTS 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.

Earthquake Deformations

GTS 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. There is also dynamic function database which includes a variety of code-based response spectra and time history functions.

Dynamic Vibrations

High-speed trains and heavy train loads are normally accompanied with strong vibrations in the track-ground system, which increases the risk of train derailment and track damages. Therefore, to allow for safer and reliable operation of high-speed trains, an investigation into the behavior of ballasted railway track foundations subjected to train moving loads at various speeds is a subject of prime importance in design of railway tracks. In this case, the sophisticated 3D numerical modelling should be developed to investigate the impact of train speed on the dynamic response of track-ground system. GTS NX support to create a railway load function from the railway load database. By simply defining a load distribution to model the train and specify the velocity, the train moving load function can be obtained automatically considering element size.

In case that adjacent structure is located near the blasting working area, safety assessment for blasting vibration is to be very important. So, influence assessment of this issue must be conducted at design stage before construction, and then safety excavation work can be performed by applying a proper vibration reduction method or measure if necessary. GTS NX support to create a blast load function from the suggested blast load formula.
