在澳大利亚Ballina建造的试验路堤的两个部分的行为，预测有限元分析之前（A级）和之后（C级）知道现场测量数据。通过将预测结果与现场数据进行比较，可以得出结论，简单的模型，如改性Cam粘土，具有可靠的模型参数值，可以产生合理的结果，通过预制垂直排水板在相对较短的时间内改善粘土质存款的性能。A类预测被判断为相当好，C类预测给出了令人满意的现场性能模拟。
The behaviour of two sections of a test embankment constructed in Ballina, Australia, was predicted by finite element analyses before (Class-A) and after (Class-C) knowing the field-measured data. By comparing the predictions with the field data, it is concluded that simple models such as modified Cam clay, with reliable values of model parameters, can produce reasonable results for the performance of embankments on clayey deposit improved through prefabricated vertical drains for a relatively short time period. The Class-A prediction is judged as reasonably good, and the Class-C prediction gives satisfactory simulations of the field performance.
