Suffusion Evaluation-Comparison of Current Approaches
The paper gives an evaluation of current practice to assess the vulnerability to suffusion. Therefore comparisons of different approaches concepts are summarized. Suffusion is characterized by the phenomena that the fines can move inside a soil skeleton. In practice the vulnerability to suffusion is evaluated in two steps. First the geometrical possibility of fine movement is analysed. If the fine particles are mobile the hydraulic conditions come into focus as triggering force. In this contribution the authors concentrate on the geometrical criteria used in current design practice. A comparison of limit state conditions and an evaluation of laboratory studies will be delivered. In addition new approaches based on statistical and stochastically methods are discussed.
