| dc.title | Impact of spatial variability in geotechnical properties on building foundations | en_US |
| dcterms.abstract | Many factors may lead to the failure of a civil engineering building, such as actions and materials, the effects of the actions and its resistances. The uncertainty of the soil properties is one of the significant influence factors on the foundation. The soil spatial variability can be analyzed using statistical methods for reliability assessment. In this project, the moment estimation method is used to display the corresponding autocovariance with the variation of the estimates. The correlation structures from both vertical and horizontal directions are established based on the SPT blow data from sites in Hong Kong. In two sites, the tendencies of the vertical autocovariance are similar (decreasing from 0.3-0.5 to zero). For the horizontal autocovariance curves, it is found that when the horizontal distance is increasing in one coordinate direction, the autocovariance for the soil properties near the ground presents a bigger change on trend. However, compared with the results of vertical autocovariance, the variation of the autocovariance in one coordinate direction does not present an obvious tendency on trend. In addition, a retaining stability study based on a simpler form of FOSM method is conducted. | en_US |
