Abstract: Shear strength parameters of soil-structure contact face are essential to soil-structure interaction subject. Experiments on soil-brick and soil-concrete contact faces by direct shear tests are conducted by direct shear tests, respectively. Effect of the decreasing contact area is verified during soil inner shearing tests. The experimental results show that friction angles of the two kinds contact faces decrease with increasing soil water content. On the other hand, their both cohesion forces and shearing strengths appear scissors shape relationship with increasing soil water content. Analysis also indicates that the soil-structure contact face behavior depends strongly on structure hydrophilic property. The experimental research results the good foundation for relative engineering design.

Key words: interface between soil and structure, experimental study, water content, shear strength, hydrophilic property
