STUDY ON SHEAR RHEOLOGIC BEHAVIORS OF SOIL IN SLIP ZONE OF A LARGE-SCALE LANDSLIDE

The shear rheologic behaviors of soil in slip zone of a large-scale landslide are studied in this paper. The samples are prepared in accordence with the gravity compaction principles and by Chen Zonglis the loading method. The rheologic behaviors of soil in slip zone are described by the Burgers visco-elastic Model. From the test results, the long-term strength parameters are obtained, and its significance in study of the stability of landslide is also discussed.
