Summary: The chapter 6. gives a general basis for the geotehnical
aspects
of the design of buildings and civil engineering works according
to Eurocode and some aspects of Croatian regulations. In the
subpart 6.1 given are some aspects of design according to
Eurocode 7 (Geotechnics) which are of general practical
importance. The subpart 6.2 describes design principles for
embankments, slopes and retaining walls, emphasising the parts
which are applicable for a design with geosynthetics. In the
subpart 7.1 described is the role of geosynthetics in a
foundation of embankments under difficult subsoil conditions.
Case history is described for the foundation of an embankment on
the see bottom at the island of Pag. In the subpart 7.2
presented are the principles of design and calculation with
modified simplified Bishop's slope stability method on high
embankments with geosynthetics. The subpart 7.3 describes the
use of geosynthetics in various types of retaining walls, models
for design by calculation and ways of execution of retaining
walls with geosynthetics.

Summary: In the centre of Zagreb in the immediate viciniti of the
railway station in the area of 32000 sq.m a garage and shopping centre were
constructed. In order to ensure the construction of a completely buried
structure with three storeys, an excavation 14.60 m deep under the ground
surface was provided. the retaining structure had to ensure the stability
of the foundation pit, adjacent buildings (Hotel Esplanade) and trafic
circulation (tramway and pedestrain subway) and to prevent water inflow in
the foundation pit and thus to provide construction of the structure. The
retaining structure consisted of a continuous reinforced concrete diaphragm
wall improwed by the prestressed ground anchors.

Summary: A plane strain elasto-plastic kinematic hardening
constitutive
equation for frictional materials has been constructed based on the power
law for small strain or elastic shear modulus, Mohr-Coulomb type shear
strength law and the normalized shear modulus reduction function which
relates the normalized shear strain and the normalized shear modulus fora
wide range of strains. The elastic shear modulus and elastic shearstrain
at failure were used as normalizing parameters. The proposed
normalized shear modulus reduction function as a unique material function
arises from the recent laboratory research on stress-strain behaviour of
soil specimens tested with high resolution local strain transducers, which
shows that the static and dynamic shear stiffness of soils follow the same
pattern. Published data on the stress-strain response of Toyoura sand
under cyclic and monotonic loading were used for the construction
of the normalized modulus reduction function in static and dynamic
analyses. The Masing type behaviour for cyclic loading is introduced by a
series of simple elasto-plastic parallel elements which may easily be
adjusted to the given normalized shear modulus reduction function. All
model parameters can directly be obtained from standard laboratory tests.

forsimulation of various field problems in two dimensions. It uses afast
and memory efficient dynamic relaxation algorithm for thenumerical solution
of partial differential field equations. Amongothers, this algorithm allows
a simple interactive controll whenconvergence to the solution of nonlinear
problems is endangered.The program allows for different constitutive
equations formechanical behaviour and various types of interactions
amongphases of two phase materials to be used simultaneously in thesame
problem. FLAC also enables anlysis of steady and nonsteadyflow through
porous media. These features render the programattractive for solving
practical geotechnical problems.

Summary: It is often necessary to reliably predict foundation soil
deformations. Overprediction of settlements in stiff clays and sands is
often encountered when based on results from laboratory tests. Recent
research has shown that overprediction occurs due to considerably greater
soil stiffness at small strains than measured by conventional triaxial
apparatuses, which normally do not provide for accurate measurements of
small strains. Further, research has shown that shear modulus reduction
with shear strain attained in monotonic tests closely corresponds to that
used in dynamic analyses, for a long time considered as inappropriate for
static loading. Consequently, devices for measuring small strains mounted
directly on soil specimens were developed, and geophysical in situ test
reaffirmed.
Three necessary ingredients for successful prediction of deformations in
stiff soils are identified through literature review: stiffness
measurements by use of appropriate in situ geophysical methods, laboratory
tests that can measure small strains, and methods of analysis that
incorporate nonlinear stress-strain behaviour of soils. Main points of the
paper are exemplified by a simplified settlement analysis of a circular
shallow foundation on a sand layer.

Summary: The seismic stability was analysed by so-called "sliding
block method" which includes the dynamic response analysis of dam, the
determination of yielding accelerations of potential sliding bodies and the
estimate of permanent dam deformation after the design earthquake.
The dynamic response was studied by variable-stiffness-shear-beam model
including the parametric analyses over the wide range of dynamic stiffness
properties of earth materials and appropriate nonlinear stress-strain
behaviour.
The input seismic parameters included several real strong-motion records
covering the wide range of frequencies. The yielding accelerations were
determined by conventional slope stability method. The estimate of
permanent displacements included the generation of appropriate diagrams
using the same acceleration time-histories as in reponse analyses.
The same method was applied in analysis of seismic behaviour of the dam
during the strongest experienced earthquake in 1990., using the original
acceleration records from the stations close to the Peruča dam location.

conditions of density and stresses is developed. Theresults of strain
controlled cyclic triaxial tests on a standardsand formed the basis for
verification of the model. Introducingthe Moroto's parameter (cumulative

between current andcritical state at equal mean pressure), results of
porewaterpressure buildup in this coordinate system fell almost on asingle
