| Abstract: | Based on three axial experiment of high pressure about Nuozadu's core materials and associated with existing experimental results, the mechanical property of seepage-proof material with gravel soil for high core dam is discussed in detail. It is pointed out that the relationship between the stress and the strain is of hard type, and soil samples reflect different mechanical characteristics under different enclosing pressures and with different amounts of gravel. These have some instructive significance to construction of earth dam. |
