Prediction of Coefficient of Consolidation Using Multi-Gene Genetic Programming

摘要

The accurate determination of the coefficient of consolidation is significantly important for analyzing settlement of clayey deposits. The coefficient of consolidation is generally determined from the consolidation test results by performing a curve-fitting method on laboratory test data. However, the consolidation test on clayey sample is quite time-consuming and expensive. This paper proposes a simple, quick, versatile, and reliable procedure to estimate the coefficient of consolidation. In this paper, Multi-Gene Genetic Programming (MGGP) model is suggested for prediction of the coefficient of consolidation from basic soil properties such as liquid limit, cation exchange capacity (CEC), pressure, void ratio, montmorillonite content, activity, exchangeable sodium percentage (ESP) and clay content.
