摘要
通过非线性有限元分析,在灰土桩顶部逐级施加荷载模拟了夯扩灰土挤密桩单桩复合地基的实际工况。对夯扩灰土挤密桩荷载沿深度方向的传递规律及沿桩体径向的土压力分布规律和夯扩挤密桩的沉降变化规律进行了分析研究,得出夯扩挤密桩的有效加固范围和土压力沿桩体径向呈钟型分布的规律等结论。
Through the non-linear finite element analysis and the dust piles at the top level-load applied to simulate the expansion of lime-soil compaction pile rammed pile composite foundation of the actual working conditions.This paper analyzes expansion of the lime-soil compaction tamping along the depth direction of pile load transfer law and the soil along the pile radial pressure distribution and tamping compaction pile settlement expansion variation,and comes to that tamping compaction pile expanded the scope and the effective reinforcement of earth pressure along the pile was bell-shaped distribution of radial and other conclusions of law.
