Abstract: A cumulative deformation forecast model can predict long-term settlement of sand under the train-induced vibration load and has a great practical value in engineering practice. Based on cyclic triaxial experiment on the remolded samples of Nanjing fine sand using GDS (geotechnical digital systems) dynamic hollow cylinder torsional apparatus, the article analyzes sand characteristics of accumuted deformation, summarizes current studies on a cumulative deformation model formula at home and abroad, and compares the different formulae results with the experiment data; finally finds the most suitable model formula for Nanjing fine sand. Through comparison and analysis, the formula of logarithm model, of which the parameters are determined, has been found having a good application effect on a cumulated deformation prediction of Nanjing fine sand.

Key words: Nanjing fine sand, train-induced vibration, accumulated deformation, prediction formula
