ABSTRACT
Construction of a very steep, 6 m high embankment for the expansion of the capacity of the existing high-voltage transformer station took place nearby nuclear power plant. A complex of geotechnical control monitoring was carried out including hydrostatic levelling gauges, pore pressure gauges, geodetic stabilized points and piezometers. Main geotechnical risk was the presence of low-bearing fully-saturated sediments of the hidden river bed of the former stream, which had passed directly below the embankment. Technology of future construction is very sensitive to uneven settlement. Values obtained via long-term monitoring were continuously being compared with mathematical modelling. Subsequently, measurements were used to determine the construction speed of the embankment.
