This paper describes (1) the determining procedure of the undrained strength of Iraqi alluvial clays for practical use and (2) the results of stability analysis for sliding of the jetty at Fao and Khor Al-Zubair, located on the mouth of the Shatt Al-Arab and on her old river channel respectively.From the considerations on the undrained strength for practical use and on the stability analysis (including the field observation), following conclusions were obtained : -(1) The undrained strength of Iraqi alluvial clays distributed along the Shatt Al-Arab should be fundamentally determined from the in-situ vane tests.(2) From the comparison of the results of stability analysis and of the field observation, it was suggested that factor of safety for sliding obtained using the undrained compression and extension strength, Su(c) and Su(e) may better represent the actual one.
