摘　　要：蓟运河防潮闸位于蓟运河入永定新河交汇口处,双向挡水,钢筋混凝土灌注桩基础。受1976年唐山地震影响,闸基出现了灌注桩顶部断裂、地基土沉陷、闸底板脱空等严重问题。针对上述问题,在不做上下游围堰的情况下,采用多种高压喷射灌浆技术对闸基进行了处理,取得了很好的效果。Jiyunhe Canal tide barrage is located at the estuary of Jiyunhe Canal where the water inpours into the Yongdingxinhe river. It is a double-side operating sluice with reinforced concrete filling pile foundation. As a result of Tangshan earthquake occurred in 1976, the foundation had several serious problems such as the breaking at the top of piles, sinking of ground and so on. To solve these problems, multiple methods of high-pressure jet grouting technology are adopted in practice and received good effect.
