Ground settlement analysis on the process of stage-filling for sott clay roadbed
摘要
Abstract
Surface subsidence in soft clay roadbed construction is inevitable. In order to warrant construction quality and roadbed stability, taking a soft clay stage-filling roadbed construction in Central China as an example, this study models the stage-filling process of soft clay roadbed construction using finite element method based on the analysis of surface settlement in soft clay roadbed, and analyzes the characteristics of ground settlement during soft clay stage-filling. The study results show that the ground cross-section settlement appears in a basin shape in the process of mollisol roadbed filling with a maximum settlement 26mm, which meets the maximum settlement standard of mollisol roadbed. The calculation method and the selected parameters are sound and reliable, and can be applied to forecast the construction process of similar projects. This study provides a technical guidance for similar soft clay roadbed construction projects.关键词
