Two case studies of settlement prediction of Ariake clay ground which is counted as one of the soft clays in Japan are described. The one of them is to report a long-term settlement which have been observed over 25 years since construction of embankment for breakwater on the coastal Ariake deposit. The another case study is concerned with the settlement of low embankment highway on Ariake clay whose shallow surface was improved by quicklime-clay mixture as a countermeasure for the settlement. It is featured by the fact that the predominant secondary settlement is common with two case studies. The finite element method using an elasto-plastic model was adopted to analyze the settlement of Ariake clay observed in above-mentioned two case studies under sustained and transient loading, respectively. It is concluded from comparison of analytieal results with observed settlement that the proposed model with consideration of secondary compression is advantageous for settlement prediction of soft clay ground.
