Geotechnical analysis of lacustrine Lake Bonneville deposits for predicting embankment settlement.

摘要

The results of a laboratory analysis, to determine geotechnical properties of lacustrine Lake Bonneville deposits, within the I-15 corridor of Salt Lake City, Utah, are presented. Laboratory vertical and horizontal consolidation coefficients from one-dimensional consolidation tests are compared with those back-calculated from observed field settlement data. Linear relationships are established between the vertical and horizontal consolidation coefficients from the laboratory data and the back-calculated values. The linear relationships are used to select vertical and horizontal field coefficients and to predict settlement rate of an existing embankment scheduled for enlargement. Conclusions are drawn from the results of the study and recommendations are given for testing and improving the model.
