USING GEOTECHNICAL DATABASE FOR MODELING SPATIAL VARIABILITY OF SOIL PROPERTIES

This paper presents a probabilistic model to determine bore-hole spacing and spatial variability of soil properties during site investigation. Using this model, it is possible to evaluate the bore-hole spacing and important soil properties for the estimation error used in reliability-design. However, this model requires correlation distance and variance of soil properties as important data input. The geotechnical data-base system for Saga plain, Japan is used to establish the relationship between these statistical variables and soil characteristics, such as, undrained shear strength, layer thickness, etc. The exploration spacing for different estimation errors is suggested for site investigation.
