摘要
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。
Model of dynamic consolidation is proposed in this paper. Nonlinear dynamic consolidation analysis program by finite element (NDCP) is compiled. Take the dynamic consolidation test of Cao Jia Bao airfield in Xining City as an example for calcuiation. The reliability of NDCP is proved by comparing dynamic stress, pore water pressure, maximum acceleration, calculated value and experimental value of ground deformation, which have the same law. Hence the mechanism of dynamic consolidation is discussod. An analytical calculation method for engineering design and theoretical study of dynamic consolidation is provided.
