对横泉水库坝体进行了强夯试验,并对其试验数据进行了整理,然后进行了理论分析,讨论了强夯的加固效果、强夯的有效加固深度、夯后填土沉陷性等。证明了采用合理的参数与施工工艺,对高填土用高能级强夯能达到10～13 m的有效加固深度,影响深度可达17 m,而且土体的压缩性、湿陷性、不均匀性都有很大改善,加固效果是很理想的。对于坝体填土,应适当控制含水量,来减少或防止夯后湿陷。
The dynamic compaction test of Hengquan reservoir dam was carried out, and the test data were sorted out. Then the theoretical analysis was carried out. The reinforcement effect of dynamic compaction, the effective reinforcement depth of dynamic compaction and the settlement of filled soil were discussed. Proved that using reasonable parameters and construction technology, the high-level dynamic compaction with high fill can reach the effective reinforcement depth of 10 ~ 13 m, the influence depth is up to 17 m, and the compressibility, collapsibility and unevenness of soil Sex has greatly improved, the reinforcement effect is very good. For dam body filling, the water content should be properly controlled to reduce or prevent collapse after ramming.
