RESULTS OF OBSERVATIONS ON A BRIDGE SUPPORT FOUNDED ON PILES

RESULTATS D'OBSERVATIONS SUR UN APPUIDE PONT SURPIEUX

The methods for the computation of the stability and settlements of bridge supports founded on piles are based on a certain number of simplifying assumptions. The Beggs-Blasek method which has already given good results in small-scale model tests of foundations of simple shapes was used to resolve the present problem. The author has endeavoured to examine the three following questions: (1) the influence of a horizontal force acting on a pile supported foundation either on vertical piles only or with battered piles at both ends; (2) the load distribution between the different piles; and (3) the settlement of the foundation as a whole. The experimental data have been compared with results computed from different known theories. A reasonable agreement was found in the case of piers consisting of vertical piles only, whereas for piers with battered piles at both ends (where the stability is 2.5 times higher when acted on by a horizontal force) the scatter is much greater and the theoretical assumptions do not seem correct. To determine the deformation of the elastic semi-infinite continuum in which piles are embedded, instead of using Boussinesq's equation which is only valid for loads applied at the surface, the author took the work of R. Mindlin as a reference. A simple function is worked out, the numerical values of which are given in tables for practical use.
