COMPUTER ANALYSIS OF A SHALLOW FOUNDATION FROM PRESSIOMETER TESTS

CALCUL SUR ORDINATEUR D'UNE FONDATION SUPERFICIELLE A PARTIR DE L'ESSAI PRESSIOMETRIQUE.

FOLLOWING THE GROWING NUMBER OF RESULTS FROM TESTS CARRIED OUT WITH THE PRESSIOMETER, THE LCPC HAS SET UP A PROGRAM ENTITLED FS72 WITH THE AIM OF PROVIDING A METHOD OF ANALYSIS FOR SHALLOW FOUNDATIONS, BASED ON THESE PRESSIOMETER TESTS. FS72 HAS BEEN ESTABLISHED FOR THE STUDY OF A SHALLOW FOUNDATION SUCH AS THAT USED IN A MOTORWAY FLYOVER. IT IS THE MOST ELABORATE CASE WHICH CAN BE TREATED BY THE PROGRAM. HOWEVER, ALL CASES ARE COMPRISED WITHIN THIS AND THE CASE WHERE THE SLAB IS SIMPLY PLACED AT THE LEVEL OF THE SOIL IS CAPABLE OF BEING CALCULATED WITH THE PROGRAM. IN WRITING OF FS72, CONSIDERATION WAS TAKEN OF BOTH THE CASE WHERE THE PRESSIOMETER PROBES ARE MADE BEFORE CONSTRUCTION AND THE CASE WHERE THEY ARE MADE AFTER CONSTRUCTION. THE SUBGRADE MAY BE HETEROGENEOUS WITH HORIZONTAL WATER TABLE, THE CALCULATION METHOD IS THAT STIPULATED IN THE FOND 72, THE GUIDE FOR THE ANALYSIS OF FOUNDATIONS PUBLISHED BY LCPC - SETRA; THE CALCULATION CHARTS PRODUCED BY L. MENARD ARE ENTERED INTO THE MEMORY BY THE PROGRAM. FS72 IS WRITTEN IN FORTRAN IV AND PUNCHED CARDS ARE USED. IT ENABLES HOMOGENEITY TO BE ACHIEVED IN THE INTERPRETATION OF THE PRESSIOMETER MEASUREMENTS AND AN OPTIMIZATION OF THE CALCULATIONS. THE PRICE IS 3 TO 5 F PER CASE ACCORDING TO THE MACHINE USED. IT WILL BE ENLARGED BY A MORE ELABORATE VERSION FS74, DEALING WITH A METHOD OF CALCULATION BASED ON THE THEORY OF BOUSSINESQ, WITHOUT THE AMENDMENTS PROPOSED BY L. MENARD.
