Direct design method of shallow foundation based on in situ tests results, application to dynamic cone penetrometer
The University G. Eiffel has built a light surface foundation test station to perform loading test campaign on experimental sites. This paper presents the test campaigns on shallow foundations carried out to failure with the contribution of optic fibre strain measurement in ground mass. Prediction of bearing capacity may be realized with direct design method based on limit resistance of in situ tests. Several methods based on limit pressure, static and dynamic penetration resistance and SPT blow count will be compared. The results are qualified with a database of 160 load tests with detailed ground investigation. This paper presents a simple, economic, and sound design method that could be easily implemented worldwide, based on a Dynamic Penetration Test (DPT) device.
