of soil of slide zone in Three-Gorge Reservoir Region caused by water[J]. 2006, 27(S1).DOI:
According to the contrastive in-situ direct shear test of the slide zone in the Three-gorges Reservoir Region in different conditions
changed rule of direct shear strength parameters and the value of c andφ which change along with water content about three kinds of soil of slide zone in different water contents conditions
such as clay
silty clay and the earth-rock aggregate
is researched. Experimental relationship between values of c andφ and water conyenton soils of slide zone is established based on plentiful data; and functionary mechanism of different characterized soil of soils zone caused by water is analyzed; then experimental formula of value of c and φ when water is sluiced or water content changes; finally softening degree of direct shear strength parameters caused by water content(water level changing) is quantified .
