AutoBlock
CAD based Program for
Analyzing the Stability of Rock Slopes and -Foundations

Topic

The rock mass - as encountered in nature - embodies a variety of discontinuities as joints and bedding planes. They weaken the rock mass and may give rise to potentially unstable blocks. If such blocks may - from kinematical considerations - move, a potentially hazardous situation may exist with regard to the stability of a slope, which needs further investigation, taking into account the loads acting and the strength properties of the contact areas.
In an area with many discontinuities a great amount of potentially unstable blocks may be found. Because often they may visually not be recognized due to the complicated and not easily surveyable topography, it is indispensable to determine potentially unstable blocks analytically using a digital terrain model as close to reality as possible.

The program "AutoBlock" covers both problems by means of a single tool. It is an add-on to the popular CAD program "AutoCAD", which allows to exploit its visualization features to its full extent. Thanks to automation and visual tools tailored for this purpose, AutoBlock allows to determine potentially unstable blocks with minimum expenditure and maximum reliability.

Obtaining AutoBlock

An evaluation version of AutoBlock may be downloaded from our FTP server (24 MB). This version is fully functional, except that the terrain surface may be modeled with up to 100 faces only. On request an unlimited version may be obtained (which may be used during one month).

If desired the evaluation version may be upgraded by inputting a valid serial number, which must be puchased from IGT:

Prerequesites: AutoCAD v. 2004 or later must be installed for running AutoBlock.
