Assessment of geotechnical properties using optimisation methods
Assessment of geotechnical properties using optimisation methods
The paper presents the results of the complex geotechnical evaluation of two sites situated on the alluvial plain of the Dâmbovita River in Bucharest, Romania, where geotechnical investigations were completed with the geophysical survey. Despite short distances between sites, the results illustrate significant variabilities of sedimentary layers and consequently of geotechnical properties. To obtain local representative correlations, we applied in the first instance several well-known formulas, but the degree of fitness was inferior. In the second stage, we developed several evolutionary polynomial regression algorithms (EPR), a method of solving optimization problems, when the objective function is nonlinear. The new predicted values were analyzed using statistical parameters and residual analysis. Thus, we obtain new formulas for each layer, allowing more precise correlations of geotechnical and geophysical parameters inside the sedimentary alluvial structure, by reporting to the relations proposed in the literature.
