    Abstract:

    An anchor cable connecting plate and ball was developed mainly for overcoming deficiency of current foundation subjected to both compressive and pull-out stresses, as well as the difficulty of construction in problematic ground conditions. The basis primarily consists of the cement soil column, the upper plate, the lower ball and the beard anchor. The cement soil column, lower ball and the beard anchor formulate the ball cable foundation, which handles the uplift force. Combining theoretical analysis with numerical simulation, the anti-tensile mechanisms of the ball cable foundation were explored, and the interaction between the ball cable foundation and soil mass was investigated. Moreover, we also studied the deformation process of the soil mass surrounding the ball cable foundation. The results revealed the evolving law of the deformation of the soil mass surrounding the ball cable, and the relationship between the uplift force and the bury depth.
