Evaluation of embankment stability on soft ground considering service loads

The stability of road embankment on soft ground is always the highlight during construction. Usually the construction is carried out on the reinforced ground and the degree of reinforcement is influenced by the methods and period. In order to evaluate such influence, changing the compression index is a simple way to represent it. Also the service load can be represented by assigning different bulk density of surcharge. Finite element strength reduction method is used to evaluate the stability of embankment at different stages.

Analysis of Geotextile Reinforced Road Embankment Using PLAXIS 2D

Geotextiles have been increasingly applied as reinforcement in road embankments on soft soil. The purpose of this study is to determine the optimum tensile strength of geotextile as the reinforcement in road embankment considering the allowable factor of safety and displacement. The stability analysis of the road embankment has been done by finite element method using PLAXIS 2D. In this study, three types of sequence modeling were conducted. First, the stability of road embankment without any reinforcement was analyzed. Second modeling was to determine the length of geotextile reinforcement considering the stability of the model road embankment. The last sequence was to investigate the stability of the model reinforced embankment with various tensile strength of geotextiles reinforcement. The result of this study showed that the optimum tensile strength of geotextiles was strongly influenced by the factor of safety.

Stabilization of embankment foundations by using stone columns

In this Technical Note a parametric study, based on Dimaggio's (1978) approach, of the reinforcing effect of stone columns on the stability of road embankments is examined. For a certain embankment geometry, stability analyses of discrete soil and stone column elements were also carried out. The results of the above analyses are compared to the results of the analyses based on Dimaggio's approach.

Stability of Road Embankments in Soft Clay

Slides in soft marine clays frequently occur during construction of road embankments in Norway. This paper outlines the routine procedure used for a stability analysis of such embankments, based on a total stress concept. Using these procedures, eight slides were investigated, and it was found that the minimum factor of safety obtained could give a too conservative picture of the actual conditions. The minimum factor of safety, which is the one normally used, varied between 0.73 and 1.10. Taking all uncertainties into consideration, an analysis based on a total stress concept as outlined herein must be considered acceptable. The study gives no basis for evaluating the accuracy of the measured shear strength values.
