Receiving this award is a great honour for me and an acknowledgement of that the long tradition of geotechnical engineering in Sweden still is in the forefront.

My research presented in my thesis (Kullingsjö, 2007) and in the article nominated to the YMA award, presented in the 17th ISSMGE Conference (Kullingsjö, 2009), deals with the deep excavations in soft clay and how the excavation will affect the immediate surroundings in terms of deformation. The uniqueness of my work is the close cooperation between academia and industry and that an exchange with outstanding universities in some areas made it possible to use highly advanced numerical analysis at a real case in the centre of Gothenburg. The research was divided into Class A predictions of a real case, field monitoring, laboratory testing, calibration of advanced constitutive soil models and Class B calculations with more or less advanced constitutive models.

It is a great honour for me to receive the Young Member Award 2009 for my publication “Scale up of BioGrout, a biological ground reinforcement method”, which I presented during the 17th ICSMGE in Alexandria, 5‐9 October 2009. In this paper I describe the experiments that were performed to develop BioGrout – a new ground improvement method based on microbially induced carbonate precipitation – from proof of principle in the laboratory to a field scale experiment, in which equipment, conditions and techniques were applied, which are also used in emphasized applications, such as increasing the stiffness of railroad embankments. First, experiments were performed in a 1 m3 container set‐up simulating a spherical injection from a single point, followed by a 100 m3 field scale experiment. In this final experiment 40 m3 of sand was biologically cemented within 12 days and 6 flushes, stretching over a distance of 5 m between three injection and three extraction points. In both scale up experiments significant increase of the average strength was obtained, but distinct spatial variability of the mechanical properties was observed. The heterogeneity is considered to be affected by the induced flow field, the distribution of bacteria, the procedure of supplying reagents (continuous flow or sequential batches) and the crystallization process.

It is pleasent surprising and honor for me to be given an opportunity to introduce my research and my views of the international society, future of geotechnical engineering in the ISSMGE Bulletin.

The paper submitted to the ICSMGE2009 was on the effect of shaking history and material properties of geogrid models on the seismic behavior of the gravity type and geosynthetics reinforced soil retaining walls, which was the part of 14‐years research achievements conducted by University of Tokyo, Railway Technical Research Institute and Tokyo University of Science, Japan. This research project started at 1995 immediately after the Hyogoken‐Nanbu earthquake so as to avoid the catastrophic failure of the retaining structures observed in the earthquake.
