强夯在红山水库坝基加固处理中的应用

Application of dynamic compaction in dam foundation reinforcement treatment of Hongshan Reservoir

红山水库坝基碾压密实度较低,渗水严重,经多方案比较,采用强夯的施工工艺进行基础加固处理,在施工过程中针对强夯的振动影响及时调整技术参数,经对强夯质量进行检测,加固效果明显,坝基土体密实度得到极大的提高,有效地降低了坝基渗流量,满足了规范及设计要求。

Hongshan Reservoir had ever seen serious seepage at dam foundation due to relatively low rolling density. Dynamic compaction technique was adopted for foundation reinforcement after comparison of multiple alternatives. Technical parameters were adjusted timely in view of the vibration influence in the course of dynamic compaction. The quality of dynamic compaction was inspected. The reinforcement renders significant effects. The soil compactness of dam foundation is greatly improved which effectively decreases the seepage up to requirements of specifications.
