针对深厚松散块石土中强夯加固机理问题，引入离散元法，采用一定级配条件下的平面圆盘模型，模拟了夯击作用下松散块石层的变形过程，反映出夯击能量在地基土中的传播特征。数值分析成果与实测资料比较，结果令人满意。 Aiming at the problem of strong ram reinforcement mechanism in deeply loose rock and soil, the discrete element method was introduced. The plane disk model under certain grading conditions was used to simulate the deformation process of the loose rock layer under slamming action, reflecting the slamming energy in the Propagation characteristics in ground soil. The results of the numerical analysis were compared with the measured data and the results were satisfactory.
