Geotechnical Centrifuge Modeling of Super-High Embankment Filled by Red Soft Soil in Western Yunnan Province

Abstract

High and even super-high embankment filled by red soft soil are often used in road construction in the mountainous areas of Western Yunnan province, China. Due to the poor engineering properties of the red soil, a proper analysis of the stability of the embankment is necessary. This paper aims to analyze the deformation and stability of a typical super-high embankment by comparing the geotechnical centrifuge modeling and FLAC-2D results. The paper finally concludes that: 1) The red soft soil in Yunnan province can be used as fill material; 2) Flat slope and geo-grid can effectively restrain the deformation of the slope; 3) Geotechnical centrifuge modeling well reflect the real engineering performance of the embankment.
