摘要
东洱河水库大坝坝基存在较厚的淤泥质黏土层及砂砾石层，上游坝坡安全稳定性较差，经计算在特殊工况下有滑动失稳的可能，因此必须对大坝上游坝脚坝基进行加固处理。阐述了振冲桩技术在东洱河大坝上游坝脚加固处理中的应用及其施工工艺，充分说明振冲桩加固技术在提高基础承载力与抗滑稳定能力方面效果显著，且具备技术成熟、经济合理、施工方便、进度快等特点，可为今后类似的工程设计和施工操作提供参考。
The upstream dam foot of East Er River reservoir dam slope stability safety factor does not meet regulatory requirements, especially in earthquake conditions, sliding instability is possible,it is necessary to carry out the upstream dam foot vibro replacement gravel pile reinforcement. This paper describes the application of vibro pile construction technology and techniques in the upstream dam foot of East Er River dam reinforcement, further illustrates the vibro pile reinforcement technique to improve the bearing capacity and the ability to effect significant sliding stability, also it has reliable technology, construction feasibility, construction speed and other characteristics, and for the engineering design and construction operation similarly in the future accumulated experience and technical reference.
