Abstract

The design and installation of safe and economic foundation solutions for large projects is of great importance in contributing to commercial success. On four recent power projects in the U.K., a variety of foundation solutions have been adopted, driven largely by the particular ground conditions encountered at each location. All four projects were gas fired combined cycle power station facilities and each location provided unique challenges in both the design and installation of the foundations. The variety of foundation soils encountered was diverse; soft alluvial peat and clay, loose to medium dense silty sands and moderately weak to moderately strong Triassic rock. Foundation solutions included shallow spread options, reinforced earth/rock fill, ground improvement and bearing piles. Various technical difficulties were overcome at each of the sites and important lessons have been learnt from these. All four power stations are similar in their design and bearing pressure requirements. The foundation solutions are all different and were selected to suit local ground conditions.

Design and Installation of Foundations in Various Ground Conditions at Four Power Stations in the U.K.

New York, New York

The design and installation of safe and economic foundation solutions for large projects is of great importance in contributing to commercial success. On four recent power projects in the U.K., a variety of foundation solutions have been adopted, driven largely by the particular ground conditions encountered at each location. All four projects were gas fired combined cycle power station facilities and each location provided unique challenges in both the design and installation of the foundations. The variety of foundation soils encountered was diverse; soft alluvial peat and clay, loose to medium dense silty sands and moderately weak to moderately strong Triassic rock.
