RELIABILITY ANALYSIS OF A TEST EMBANKMENT BY VARIANCE REDUCTION AND NEAREST-NEIGHBOR METHODS. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

The probabilistic evaluation of settlement and stability of an Asian Institute of Technology (ait) test embankment has been carried out using three-dimensional variance reduction method and two-dimensional nearest-neighbor methods. Statistical data of the occurrence of fine sand and silt lenses in the soft Bangkok clay were obtained and probabilistically simulated to investigate their effects on the settlement prediction. The effect of radial drainage is taken into account under plain strain condition using the method of Lacasse (1975). Probabilistic settlement prediction using the method of Skempton and Bjerrum (1957) showed reasonable agreement with the observed values. Horizontal and vertical autocorrelation functions of the undrained shear strength were obtained using the field vane shear strength. Probabilistic slope stability analysis using the three-dimensional variance reduction method appeared to be more rational approach than the two-dimensional nearest-neighbor method. Including a 5% model error, the probabilities of slope failure of the test embankment at the final stage were 0.00000069 and 0.000023 for the two-and three-dimensional analyses, respectively.
