Assessment of the impact of soil degradation due to pile driving on slope stability
Assessment of the impact of soil degradation due to pile driving on slope stability
Piles are a common foundation solution to support buildings, bridge abutments and embankments in soft soil deposits to transfer structural loads to deeper more stable soil layers or bedrock. During pile driving adjacent to slopes, stability of the slope can be negatively affected due to excess pore pressure generation, dissipation of the excess pore pressure into the slope, induced displacements, and cyclic degradation of the soil among other possible factors. However, there is a lack of understanding of the failure mechanisms involved in this phenomenon; as well as methods to account for the temporary reduction in slope stability during pile driving. This paper provides an overview of this problem. Furthermore, the paper introduces a method which couples pile driving analysis using wave theory with numerical finite element analysis to obtain the extent of cyclic soil degradation due to pile driving. This could be further used to assess stability of a slope during pile driving.
