抛石挤淤法是道路穿越山区湖区经常采用的一种建造路基的方法。在江西省某穿越湖区的抛石挤淤路基中,布置了3个试验区,分别为普通区、强夯区和反压区,用来研究这3种不同形式的抛石路基的变形特性。结果表明,反压路基和强夯路基可以有效的提高抛石路基的稳定性,减小抛石路基的侧向位移以及沉降,而强夯法的效果要更好一些。在反压布置有困难的情况下,可以采用强夯法来解决穿越山区湖区道路的稳定性问题。
The riprap method is a commonly used method of building subgrade through the mountain lakes. Three test areas were arranged in the riprap embankment of a certain crossing lake in Jiangxi Province. They were general area, compaction area and backpressure area, which were used to study the deformation characteristics of the three different types of riprap embankment. The results show that the anti-pressure subgrade and the strong ramming subgrade can effectively improve the stability of riprap subgrade and reduce the lateral displacement and settlement of riprap subgrade, but the effect of dynamic compaction method should be better. In the case of back pressure arrangement difficulties, the dynamic compaction method can be used to solve the stability of the road through the mountain lake.
