The deformation and strength characteristics of damaged remolded expansive soil are studied by the tri-axial tests of different bore diameter damaged expansive soil. The results show that the area and location of cylindrical bores have significant effect on the mechanical and deformation characteristics of the soil. Little damage can improve the shear bearing capacity of the specimen; but when the damage is large, the bearing capacity of the specimen is weakened with the increasing damage. Under the same shearing conditions, partial strain is less than 7%; the specimens with same damage area and different damage locations have the same force form; while if the partial strain exceeds by 7% in the same damage area, the bores are closer to the center of the specimen and the shear strength is smaller.
