SLOPE STABILITY ANALYSIS OF ELEVATED SHORLINE AT BALATONFÖLDVÁR
Over the past decades, discernible trends of continuous erosion and localized failures have manifested along the
Balatonföldvár high coast (near Lake Balaton). These erosional processes have eroded the cliffs and instilled
profound concerns regarding the structural integrity of residential structures and transportation routes close to
the elevated cliff edge. It is necessary to note that vital transportation networks, including roadways and
railways, are located beneath the high coast, intensifying the urgency of grappling with the stability issues
engendering this geological feature.
The overarching aim of this research is to gain a clear understanding of the geotechnical elements that govern
the high coasts stability. This involves a comprehensive state-of-the-art evaluation of existing literature,
gathering historical data on laboratory tests of soil specimens collected from the site from different layers.
These data sets made it possible to determine an accurate soil profile with appropriate physical parameters.
Cross-sections were compiled from the area using archive drilling data and on-site observations. The slope
stability was modelled with computer code Geo5. Input parameters were determined for each modelled layer
and included dry and saturated unit weight angle of internal friction, cohesion, Poission ratio and modulus of
elasticity. The failure surfaces were obtained using the computer code, and the slope stability was calculated for
dry and saturated conditions. The current factor of safety was determined, and the possible failure surfaces were
identified. The significance of this examination is underscored by its relevance to adjacent residential
settlements, roads, and rail networks. Furthermore, it is highlighted by historical instances of catastrophic
failures affecting analogous geological formations surrounding Lake Balaton.
