摘要: 介绍重庆江北嘉陵江防洪护岸工程高填方的强夯加固现场试验,并采用有限元方法对强夯处理高填方的过程 进行了数值模拟,数值分析与现场试验结果吻合较好.研究表明,高填方经过强夯处理后,土体发生了较大的沉降变 形,密实度和承载力有较大幅度提高;采用有限元方法对高填方强夯加固处理进行数值分析是可行的,能够模拟高 填方地基土在强夯冲击荷载作用下的弹塑性动力响应.

关键词: 强夯, 高填方, 现场试验, 数值分析

Abstract: A site test of dynamic consolidation for high earth fill of Chongqing Jiangbei Jialing River flood embankment engi- neering was introduced,and the process of dynamic consolidation was simulated by FEM.The numerical an alysis results are basically consistent with those of site tests.It could be seen that a biggish settlement deformation Was produced in soil by dynamic consolidation,and the consistency and bearing capacity of soil advanced to a great extent.At the Salne time,it indicates that numerical analysis for dynamic consolidation by FEM is feasible,and it could preferably simulate the elasto-plastic dynamic response of higll each fill ranlmed by impact load.

Key words: dynamic consolidation, high earth fill, site test, numerical analysis
