摘　　要：根据糯扎度心墙料高压三轴试验,结合已有的试验研究成果,对掺砾混合土料用作高坝心墙防渗料的静态力学性能,进行了较为系统的论述,指出了其应力应变关系呈现硬化型,以及土样在不同围压,不同砾石含量下表现出的不同力学特性。对今后土石坝工程心墙料的选取有一定的指导意义。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 oore 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.
