Abstract [en]

Geotechnical design is important to ensure good stability and bearing capacity of the

ground. A part of this is to make good forecasts of future settlements. Nowadays

most calculations are made in computer programs, such as Novapoint Geosuite

Settlement. Geosuite Settlement includes a variety of calculation models, where some

of the models include an addition of creep behaviour.

The main purpose of this diploma work is to compare the results from different

geotechnical settlement calculation models in Geosuite Settlement. As a reference

object, an undrained test bank on clay in Lilla Mellösa outside of the community

Upplands Väsby was selected. On this test site, the Swedish Geotechnical Institute

(SGI) has performed measurements of long-term settlements since 1947.

The result of this diploma work shows that the calculation models containing creep

give result more like the measured settlements, than the calculation models that do

not include creep. Despite of this, the measured settlement is greater than the

settlement in calculation models containing creep.

The most remarkable in this work are high excess pore pressures when using models

containing creep. These excess pore pressure, in the result of this work, also

decreases very slowly in time.

One conclusion of this diploma work, based on the obtained results of this study, in

comparison with other studies, is to use a calculation model containing creep, if the

conditions are similar to those at the test site Lilla Mellösa.
