Geotechnical Analysis Support Service
3D stress deformation analysis program with the finite-element method (FEM)

FORUM8 have started providing "Geotechnical Analysis Support Service" that is a service to create a model mostly "ground" and initial data of not only 2D model of GeoFEAS2D but also 3 D model for users using "Geotechnical Finite element Elastoplastic Analysis Software (GeoFEAS) 3D".

When we have to concern symmetry such as load or shape, it can be required 3D analysis, for example, prevention pile for landslide, crossing part in a tunnel, ain deliberation about construction influence around pile foundation and so on. Moreover, regarding an interaction between construction and ground, such as a torsional moment can only be analysed by 3D. Thus as we create a model based on an actual construction, to do economical and rational analysis, we think 3D analysis can be necessary in many cases.

To use 13 different type of clayfs constitutive law to nonlinear of ground for static issue, it is capable to create a proper model for analysis object so that you could get deformation or stress distribution. And using a bunking of ground or stage analysis involved in cutting, interaction analysis with construction, stability analysis involved in heading, shear strength reduction method, we can do stereoscopic stability analysis for slop or landslide.

Our staffs in technical team and developing team back you up. Especially regarding "FEM analysis", this service provides a series of process such as creation data which is most troubling and treatment of analysis result needing operational technique, visualisation. We also have a system to make a quotation to check our service price. Basically, it calculates based on number of points and stage.

It can be a side but GeoFEAS3D has various useful function‚“ to operate easily in pre and post part. The input window of the Pre processor part has useful functions to create 3D models. It is easily available, dividing constructions or grounds into each group, color cording on display, switching display / hide, as well as normal functions to enlarge / reduce size, define work plane, display as solid / plane / perspective view. The output window of the Post processor allows contour / vector display of stress-strain relation as wells as a deformation diagram. This case is showing the combination of deformation and stress contour diagram.

CASE1 Foundation
This is the case of the examination for affection of vicinity construction of existed pier. The ground deformation or the stress increment of the pile body can be calculated when tunnel construction was carried out near the pier with pile foundations. In this case ground layers are divided into three layers; load bearing layer, middle layer and surface layer. The input window allows easy setting of the material property or coordinates by using the color cording function. This analysis model set as plate elements with steel pipe piles and a lining on the tunnel are represented as realistic for the ground affection. Though the stage setting allows you to analyze the initial stress and to set detailed settings along tunnel evacuation, this example provides only the finale stage.
