通过ABAQUS有限元模型,分析了重庆山区典型填土地基的强夯振动规律和对既有建构筑物的影响,结果表明:强夯作用下,水平速度和加速度变化大于垂向速度和加速度,强夯对已有建构筑物的振动影响主要集中在顶层框架,实际应用中,应加强对结构顶层框架数据的测试,保证建筑物的安全。 Through the ABAQUS finite element model, the dynamic compaction and dynamic compaction of the typical landfill in Chongqing mountainous area are analyzed. The results show that the change of horizontal velocity and acceleration is greater than the vertical velocity and acceleration under dynamic compaction, The vibration of the existing structures mainly concentrated in the top frame, in practice, should be strengthened on the structure of the top frame of the test data to ensure the safety of buildings.
