| Abstract: | This paper presents a case history on settlement monitoring results on an airport constructed with high fills.Several settlement estimation methods of high fill ground are examined with the observed data.The paper analyzes the settlement characteristics of the fill materials as well the original foundation soils.Different settlement prediction models,such as e-p curves,loge-logp model,empirical relationship as well as the numerical models are established from the large diameter triaxial test results.The settlement of the high fills are predicted by several different methods,such as,log-log model,summation of sublayers as well as numerical analysis.The advantage and disadvantage of these settlement prediction methods are compared with the observed data. |
