Abstract | There are two ways to obtain the geotechnical design parameters. Parameters obtained using the conventional laboratory test results are subjected to the sample disturbances and the changes in the effective stress of the soil samples during sampling. Therefore, the new trend of parameter determinations is by using the interpretation of in-situ test results. However, the limitations of sound theoretical background for the in-situ tests lead to a situation in which almost all present interpretation techniques are empirical. For different deposits, with different sedimentary environment and stress hist01y, the empirical correlations of in-situ test is probably different. Therefore, for a specific deposit, before using the parameter obtain from the in-situ test results in design, the validity of the existing empirical correlations has to be ve1ified or modified if necessa1y. Taipei Silt Fo1mation (TSF) is the recent deposit in the Taipei basin with thickness of 40-70 meters. Due to its high compressibility and low shear strength, the property of this formation is of interest to the local enginee1ing practice. Therefore, the validity of those established in-situ test empirical correlations need to be ve1tified or modified for this formation before it can be used in practice to estimate design parameters. Four standardized process in-situ test results, Piezocone (CPTU), Dilatometer (DMT), Field Vane Shear Test (FVST) and Pressmemeter (PMT) tests, have been collected to evaluate the enginee1ing prope1ties of cohesive soil in TSF. Using these results and the corresponding laborat01y test data, attempts are made to update these published empirical correlations of the soil classification and stratigraphy, undrained shear strength, stress histo1y and coefficient of consolidation for clay soils of TSF for its use in the local engineering practice. |
