According to high backfilling project in South America, through a large number of laboratory tests data and field vane shear test results, the engineering characteristics of marsh peat soil in this area are analyzed, and the variation of the shear strength of the peat soil along the depth and the sedimentary characteristics are demonstrated. The selection principle of the calculation index of the foundation for the high-filling operation of peat soil foundation is proposed. It has reference significance for similar engineering construction.
