高速公路高填方路基强夯补强施工及现场试验研究

Study on Dynamic Consolidation Construction and Field Test of High Fill Subgrade of Expressway

文中结合某高速公路扩建工程实例,对高速公路高填方路基强夯补强施工技术及施工效果进行分析。结果表明,对路基进行强夯补强后可减少38.5%的沉降量,土体压实度提升了9%~23%,而有限元法和瑞利波检测法的计算结果与实测结果十分接近,说明了两种测试方法的可靠性。

Based on the example of an expressway expansion project,this paper analyzes the construction technology and construction effect of dynamic compaction reinforcement for high fill subgrade of expressway.The results show that the dynamic compaction of the subgrade can reduce the settlement amount by 38.5%and increase the soil compaction degree by 9%~23%.The calculated results of finite element method and Rayleigh wave detection method are very close to the measured results,which shows the reliability of the two test methods.
