Abstract

The Compañía Sevillana de Electricidad, S.A., is building a fuel power plant near the mouth of the Guadarranque river in the Algeciras Bay, in the South of Spain. The site is flat, with the ground water level close to the surface and occasionally above it, giving the site a marshy aspect. The thickness of the alluvial soils is such that deep foundations have been considered so expensive that an alternative solution has had to be sought. The rather loose and granular characteristics of the soil deposit caused some concern about settlement of shallow foundations in addition to the risk of liquefaction. After selection of the proper method, the upper part of the soil has been vibrocompacted and the foundations built on spread footings or small floating piles (some heavier elements). Ground improvement control, pile loading testing, recorded settlements and other interesting features of this large project are given in this presentation.

Power Plant Construction on a Thick Sand Deposit

The Compañía Sevillana de Electricidad, S.A., is building a fuel power plant near the mouth of the Guadarranque river in the Algeciras Bay, in the South of Spain. The site is flat, with the ground water level close to the surface and occasionally above it, giving the site a marshy aspect. The thickness of the alluvial soils is such that deep foundations have been considered so expensive that an alternative solution has had to be sought. The rather loose and granular characteristics of the soil deposit caused some concern about settlement of shallow foundations in addition to the risk of liquefaction. After selection of the proper method, the upper part of the soil has been vibrocompacted and the foundations built on spread footings or small floating piles (some heavier elements). Ground improvement control, pile loading testing, recorded settlements and other interesting features of this large project are given in this presentation.
