摘要
以目前常见的斜坡地基填筑路堤为工程原型,采用基于强度折减的有限单元法,全面分析不同地基环境条件、地基坡度等不同组合情况下斜坡地基填筑新路堤的整体稳定性与沉降变形规律,并通过离心模型试验对分析结果进行验证,为类似工程的设计提供技术支撑。
Taking currently common filling embankment on slope foundation as the project prototype, this paper adopts finite element method （FEM） based on strength reduction to fully analyze the integral stability and laws of sediment and deformation of filling embankment on slope foundation in different combinations of various environmental conditions and slopes of the foundation, and verifies the analysis results via the centrifugal model test so as to provide technical supports for design of similar projects.
