PRJ PR 11 Foundations in chalk
Provides guidance on the selection and design of shallow and piled foundations in chalk. The report presents a scheme for the engineering classification of chalk in foundations, and gives the results of re-interpretation of numerous plate and pile loading tests. Design procedures for shallow foundations including advice on construction aspects and the treatment of dissolution features are proposed. Analysis of the results of pile testing lead to recommendations for the design of bored, CFA, driven cast-in-place and preformed piles in chalk and for the estimation of shaft and base resistances. Guidance is given on the choice of shallow or piled foundations and on pile selection.
Supersedes PG 6. Based on research project 458.
