Soil Improvement of Alluvial Deposits Under High-Speed Railway Embankment: Field Case Study
Abstract This paper describes the performance of the Moroccan high-speed railway embankment over alluvial soft ground treated with prefabricated vertical drains. For analyzing soil behavior, numerical analyses were performed under 2D finite element Plaxis code. The authors undertook Class-B prediction at first, using two different constitutive models, soft soil and soft soil creep (SSC) models. Class-C prediction was then performed using only SSC. By comparing the predictions with field measurement, it was concluded that the time-dependent model (SSC) produced acceptable results . However, reasonable modification for the SSC model input parameters in Class-C prediction led to obtain accurate matches with field measurements.
