Development of The Method on The Prediction of Soil Plat Penetration Resistance

Abstract During operation, the lug wheels penetrate the soil and form certain angle to the soil surface at varying penetration depths. In order to determine the soil reaction force against plate penetration given to the soil, penetrometer was mounted on the plate. Plate sizes used in this experiment were 5×5 cm2, 5×10 cm2, 5×15 cm2 and 5×20 cm2. The measurement was carried out at varying angles and depths i.e. 90°, 75°, 60°, 45°, 30° and 4 cm, 8 cm, 12 cm and 16 cm, respectively. The objective of this research was to develop the method on the prediction of soil plat penetration resistance at varying depths and angles. Prediction method was developed using linear or polynomial regression method which compared with Artificial Neural Network (ANN). The research showed that ANN generated better prediction value which indicated by lower error magnitude compared with regression method i.e. 9.9% and 19.7%, respectively.
