摘　　要：介绍了蚌埠朝阳淮河公路大桥利用高压旋喷竖直帷幕止水技术加固地基、减少大型双壁钢围堰入土深度进行水中承台施工的技术及工艺 ,特别是在加快工程进度 ,缩短施工工期 ,降低工程成本方面具有显著效益 ,可供同类型工程参考。In the aquatic base slabs construction of the Bengbu Chaoyang Huaihe River Highway Bridge, the high pressure chemical churning vertical curtain wall water-seal method was adopted to reinforce the bridge foundations and to reduce the depth into the dust of the large-scale double wall steel cofferdam. These technologies mentioned above can bring remarkable benefit at cutting down time limit for a project and reducing engineering cost etc.
