How robust is the method of analysis?
You always get a solution. The Ordinary Method of Columns always gives an answer. As does our implementation of Spencer’s Method in 3D which calculates and reports the out of balance forces and moments, thus providing an estimate for "error" of the result. We do not have an error message algorithm failed to converge.
Why does TSLOPE only have two methods for analysis?
We have implemented the Ordinary Method of Columns (OMC) and Spencer's method for both 2D and 3D. The direction of sliding calculated by the OMC is needed as a starting point for Spencer's method in 3D so that you always get the OMC result, even if you specify Spencer’s method. Spencer's method in 2D and 3D is able to satisfy full force and moment equilibrium and is the most stable of such method that “fully satisfy equilibrium”. There is just no point offering other methods which you will rarely if ever use.
Can you do seismic analyses with TSLOPE?
Only pseudo-static analyses. But an automatic search for the critical seismic coefficient is included. This can then be used in various simplified methods of computing deformations. See for example Treasure Island case study. We are, however, working on the addition of the computation of displacement using the Newmark method using user-specified site-specific acceleration histories as input
How do I get my model into TSLOPE?
The best way to generate your slope model is to use your geological modelling system, or CAD package. The 3D surfaces can then be transferred as a cloud of points, or in dxf, or obj format into TSLOPE.
I only have a 2D section showing my slope!
You can import the table of points defining your 2D slope into TSLOPE or specify them by hand. There is a tool for extruding this into a 3D model with the assumption that there is no change in slope geometry away from the location of the 2D section. In due course we will offer converters for other popular slope stability programs.
Are there any other payment options available?
We recommend that you use the credit card payment option if at all possible. If you need to use some other method of payment, then you should contact us at email@example.com.
