GEOTECHNICAL DATA BANK FOR INDIANA
Abstract
Efforts to extract the geotechnical information contained in the subsurface investigation reports held in the files of the Indiana State Highway Commission (ISHC) have extended over several years. A total of 9442 sets of data have been stored through early 1978 to mid 1979. Both conventional and nonparametric statistical methods were employed. The data were grouped by using physiographic region or engineering soil classification, or soil association, or a combination of them. One-way classification, two-way classification, and factorial experiment layouts were used to examine the distributions of the data. Regression analysis was used to investigate the functional relationships between design parameters and index properties. Topographic features were found to be significantly different among physiographic regions. Remolded soil characteristics were also evaluated and contrasted between physiographic regions but also within AASHTO classifications. Statistical soil profiles were developed showing the relations of soil characteristics versus depth for soil association within a physiographic region. Finally, soil design parameters were estimated by using index properties.
