Efficiency gain by automated embankment stability analysis

By regulation, the safety of Dutch river embankments must be assessed each five years. Such an assessment was executed in 2002/2003 for the area "Noord-Holland". The assessment involves the geometry definition and stability analysis of thousands of crosssections, followed by an inspection to find the critical parts. The assigned project engineer states: "This job would not be possible without the automated geometry generation and analysis by MGeoBase. It saved me lot's of time and allowed me to concentrate on the results instead of the labor".

MGeoBase reads surface descriptions from the existing Geografical Information System, and combines them with probabilities of different soil profiles in order to generate different geometrical cross sections. One button click is then sufficient to start the stability analysis of all cross-sections. Each stability analysis is performed by the integrated MStab program. The critical cross-section results are found simply by browsing directly from MGeoBase. The probability of failure has also been visualized on top-view maps, in order to give a quick impression of the critical parts.

All relevant data has been stored implicitely in MGeobase's database. This means that the next assessment can be executed even more efficiently, because it only takes the modification of changed loads and properties in order to start the re-analysis and re-interpretation. The systems also allows a quick safety scan during measured high water levels.
