ABSTRACT

The contemporary construction on the territory of Sofia requires more and more
responsible execution of the geological researches. The drilling of deep construction
pits, as well as the construction of high-rise buildings (with more than 100 m height),
are connected with serious problems, especially in the anti earthquake security
insurance.

One of the important questions which were raised in the construction of Metrostation 7
in the Sofia’s centre, as well as in the designing of Europa Center, having 180 m office
tower, is the obtaining of the dynamic characteristics of the soils and the possibility of
liquifaction of the shallow situated water saturated sands.

Many test, in which the also author participated, were conducted to help solving this
questions. The results from those tests, as well as the conclusions drawn from them, are
presented in the report. There are also some recommendations about the requirements
for the geological researches and safety in the designing of buildings in similar
conditions.
