Technique for Estimating the Cone Bearing Smoothing Parameters

Cone penetration testing (CPT) is an extensively utilized and cost effective tool for geotechnical site characterization. CPT consists of pushing at a constant rate electronic cone into penetrable soils recording the resistance to tip (qc value). The measured qc values (after correction pore water pressure) are estimate soil type associated properties based predominantly on empirical correlations. most common tips have areas 10 cm2 15 cm2. Investigators also significantly larger (33 40 cm2) so that gravelly can be penetrated. Small (2 5 shallow investigations. particular depth affected by above below interest which results in smoothing or blurring true bearing values. Extensive work has been carried out mathematically modelling function blurred measurements. This paper outlines technique facilitates estimating dominant parameters from processing real data sets. calibration referred as so-called CPSPE algorithm. mathematical details algorithm outlined this along with challenging test bed simulation.
