摘要
压实系数是控制路堤填筑的关键性指标。本文通过分析不同压实系数下的强度特点以及通过离心试验和有限元对不同压实系数路堤沉降的模拟,得到粘聚力c值和摩擦角φ与不同压实系数的关系以及不同压实系数下路堤沉降的特点,为路堤填筑提供了重要的依据。
Compaction degree is the key index of embankment is simulated by centrifugal test to control construction of embankment. In this paper the settlement and FEM analysis under different compact degrees, and the relationships between cohesion, friction angle and compact degree and characteristics of embankment settlement under different compact degrees are obtained ,which provides important basis for construction of embankment.
