砂砾石振冲桩施工在水利工程中的技术应用

Application of the Technology of Sand and Gravel Vibroflotation Pile Construction in Water Conservancy Engineering

新疆某水利工程坝基为砂砾石基础，主要通过振冲碎石植对其加固处理。本文结合工程泄水闸坝基加固方案，着重介绍了振动沉管碎石桩施工工艺、施工方法和施工过程中的质量控制。

The dam foundation of a water conservancy project in Xiangjiang province is of sand and gravel, and its reinfo-rcement was completed by the use of gravel stone. Combining with the engineering of reinforcement scheme of sluice gate foundation, the paper introduced emphatical y the vibration si-nking tube gravel pile construction technology, construction method and quality control in the process.
