In this research area, we are developing geotechnical calculation methods, to improve the reliability of calculations, especially in challenging soil conditions. This includes both ultimate limit state (ULS) and serviceability limit state (SLS) analysis comprising subjects such as slope stability, earth pressure/retaining walls, settlement, and foundation structures in general. It is important to have a holistic understanding of soil behavior, its parameters, the ways to determine them as well as soil-structure interaction (SSI), when necessary, to improve and develop new calculation methods.
Background
We have been strongly committed to developing the geotechnical calculation package Geocalc (Civilpoint). In the RASTAPA project, we developed and improved stability calculation methods, especially that of old embankments. The MASI project will focus on earth pressure and retaining walls. A general goal is to implement the research results in practice. The Geocalc calculation program is a good example of implementing state-of-the-art calculation methods from international research co-operation into daily engineering work. In addition, for example, the results of the RASTAPA project have been implemented into practice both in design guidelines and in Geocalc program.
Goal
The challenges in foundation engineering are growing as cities become densified, the availability of good land reduces, and old wastelands are taken into service. Finland is characterized by soft soils whose strength and deformation properties are very poor, which increase the risks when constructing on such sites. On the other hand, the accuracy and reliability of design calculation must be improved to secure safe and more economical construction.
