A CASE STUDY OF LIQUEFACTION ASSESSMENT USING SWEDISH

Evaluation of liquefaction potential of soils is one of the important aspects of geotechnical earthquake engineering practice. After the publication of “simplified procedure ” in 1971, it has become a widely used method of practice for liquefaction assessments. Several in-situ tests have been used for evaluating resistance of soils to liquefaction. The most common are SPT, CPT, Vs measurement and BPT. Swedish Weight Sounding test is a common in-situ test in some countries like Nordics, Japan and some east European countries. Also, It has been used in Iran for geotechnical design purposes in some projects. The paper presents a case study of using Swedish Weight Sounding results to assess liquefaction potential in Shahid Rajaei Port development in Iran, which is a very large development plan. The site consists of reclaimed sandy areas filled with dredged materials. An extensive geotechnical site characterization program has been undertaken in the project using different tests such as SPT, CPT, Dynamic Probing and laboratory tests, as well as Swedish Weight Sounding for research purposes. Regarding the case study of the mentioned project, the paper concludes on the validity of using Swedish Weight Sounding for liquefaction assessment
