Evaluation of Stresses in Saturated Sand Deposit Subjected to Traffic Loads
交通荷重を受ける飽和砂質地盤の地中応力の評価
About This Article
Descriptions
The present study aims at surveying earth pressures induced by traffic loads in soft soil deposits and developing an analytical method for evaluating the stresses due to such loads. Vehicle running tests were performed on the low embankment which was under construction on saturated alluvial sand deposit with very low standard penetration value. Earth pressures were measured at some points in the fill and base ground during the vehicle-running tests of various running speed. The observed distribution of vertical pressure was compared with the calculated values by both Boussinesq's equation and dynamic finite element method with has been developed by the authors. As the result, it was understood that the measured vertical pressures were several times as large as those of the results of Boussinesq's equation while the calculated results by the present dynamic finite element analysis agreed well with the observed ones.
