摘　　要：从石墨混凝土棱柱体试件单轴压缩全过程试验结果可以看出:无论在单次还是反复荷载作用下,混凝土割线模量-应变关系与电导率-应变关系的走势均保持一致,再由比拟法论证得到石墨混凝土电场-力场可作受荷全过程比拟。Prism-shaped specimens of graphite concrete are tested for their electrical and mechanical properties through the whole compression process. The results show that the deformation modulus-strain and conductivity-strain relationships are obviously correspondent with each other under both single and cyclic loading. Method of analogy is applied to prove positively that the electrical and mechanical fields of graphite concrete can be analogized in the whole loading process.
