摘　　要：为研究某散货码头堆场由于荷载使用条件的改变,在新荷载条件下地基土体的位移和稳定性,采用PLAXIS 3D软件建立三维有限元模型,对堆场地基进行水泥搅拌桩加固模拟分析。结果表明,经水泥搅拌桩加固后的地基最大沉降量为0.393 9m,最大水平位移为0.170 9m,水泥搅拌桩加固能有效减小土体位移,提高堆场的整体稳定。In this paper, the displacement and stability of foundation soil mass of a bulk dock yard under new load conditions are studied due to the change of load operating conditions. Three-dimensional finite element model is established by PLAXIS 3D software to simulate the reinforcement of cement mixing piles on the foundation of the yard. The results show that the maximum settlement and horizontal displacement of the foundation reinforced by cement mixing piles are 0.3939m and 0.1709m respectively. Reinforcement with cement mixing piles can effectively reduce the displacement of soil body and improve the overall stability of the yard.
