Abstract

Very little good field data exists concerning the performance of heavily loaded end-bearing piles on thin layers of weak rock. The problems associated with the foundations for silos are often severe, since loads are normally heavy, and allowable differential settlements are often very small. The paper describes just such problems, associated with the construction of a flour mill complex, where the principal problems were associated with the uncertainties of pile performance. On the basis of the uniaxial unconfined compressive strength of the supporting rock the end-bearing piles supporting silos within the mill appeared to be overloaded. A programme of slow maintained load pile tests demonstrated that the piles in fact performed very well. Long term settlement records of the loaded structure have confirmed this.

Foundation Design and Construction for a Large Mill Complex

Very little good field data exists concerning the performance of heavily loaded end-bearing piles on thin layers of weak rock. The problems associated with the foundations for silos are often severe, since loads are normally heavy, and allowable differential settlements are often very small. The paper describes just such problems, associated with the construction of a flour mill complex, where the principal problems were associated with the uncertainties of pile performance. On the basis of the uniaxial unconfined compressive strength of the supporting rock the end-bearing piles supporting silos within the mill appeared to be overloaded. A programme of slow maintained load pile tests demonstrated that the piles in fact performed very well. Long term settlement records of the loaded structure have confirmed this.
