冲击式压路机压实效果的有限元分析

摘要

Based on finite element simulation software ABAQUS,the process of impact roller compacting subgrade was simulated and analyzed by using the method of transient dynamics. The compactness and settlement variation of subgrade under the compaction of impact roller was studied. Compared with field test data,point out the numerical simulation results are in good agreement with the field test results,this shows the numerical results have a good reliability.%基于 ABAQUS 有限元模拟软件，用瞬态动力学的方法，对冲击压路机碾压路基的过程进行数值模拟分析，研究路基密实度和沉降在冲击压路机碾压作用下的变化情况，并与现场试验数据作了对比，指出数值模拟结果与现场试验较为吻合，具有较好的可靠性。
