EFFECT OF DISTURBANCE ON PARAMETERS DERIVED FROM SELF-BORING PRESSUREMETER TESTS IN SAND

A series of field tests has been performed to investigate the effects of drilling disturbance on the values of the parameters derived from self-boring pressurementer tests in sand. The approach adopted consisted of using different drilling shoe and cutter geometries, thereby deliberately causing varying amounts of drilling disturbance. The results show that the values of friction angle and dilation angle are sensitive to drilling disturbance. A procedure for correcting for the effects of drilling disturbance is proposed; however, it is demonstrated that the best results are obtained when drilling disturbance is kept to a minimum.
