针对超大粒径块石间距与其间土石混填料压实度之间的关系问题,采用室内试验和数值模拟的手段,分别对不同间距下土石混填料的压实度和夯击沉降量等数值进行分析。结果表明,超大粒径块石间距大于夯锤直径时其间土石混填料在标准夯实下压实度可以得到保证,为实际工程提供了指导。 Aiming at the problem of the relationship between the distance between large-size block stones and the compaction degree of soil-stone mixed materials, indoor tests and numerical simulation methods were used to evaluate the compaction degree and the amount of tamping settlement of soil- analysis. The results show that the compactness of soil-stone mixed material under standard ramification can be guaranteed when the distance between oversized block stones is larger than the diameter of rammer hammer, which provides guidance for practical engineering.
