모형토조실험을 통한 말뚝지지력의 평가
Evaluation of Pile Bearing Capacity using Calibration Chamber Test
초록
Static formulae based on limiting equilibrium theories often provide misleading predictions of pile bearing capacity in cohesionless soils due to the incorrect basic assumptions or oversimplification of actual soil conditions. Soil conditions prior to pile driving are significantly changed after pile installation and imposition of high stress levels. Therefore soi1 parameters at failure rather than those obtained at initial conditions should be used in application of static formulae. In this research. model pile test data were analyzed and compared with the predicted values obtained from the various static formulae. The results showed that the proper choice of soil parameters remarkably improve the reliability of static formulae.
