本文提出了强夯的模型,编出了强夯问题的(动力)弹塑性有限元程序(NDCP)。以西宁市曹家堡机场强夯试验为例,进行计算,比较了动应力、孔隙水压力、加速度最大值,地面变形的计算值与实测值,规律相同,证明NDCP的可靠性,从而探讨了强夯的机理,为强夯的工程设计和理论研究提供了分析计算方法。 This paper proposes a powerful model and compiles the (dynamic) elasto-plastic finite element program (NDCP) for the dynamic compaction problem. Taking the strong ramming test of the Caojiapu Airport in Xining as an example, the calculations were performed to compare the dynamic stress, pore water pressure, maximum acceleration, and calculated values ​​and measured values ​​of the ground deformation. The same rule was used to prove the reliability of the NDCP. The powerful mechanism provides analytical calculation methods for powerful engineering design and theoretical research.
