摘　　要：针对河床冲刷严重,岩体倾斜,裸露无覆盖层,不能进行水下爆破等特殊情况,创造性地提出了异形钢围堰的新技术,并对异形双壁钢围的混凝土封底技术及施工工艺进行了研究,对施工中出现的一些问题提出了解决方案。成功地在不进行水下爆破的情况下完成水中承台的浇筑施工,以期能够为相似工程的建设提供借鉴。Aiming at the serious erosion of the riverbed, rock slope, bare and non covered, no underwater blasting and other special circumstances, creatively put forward the new technology of special-shaped steel cofferdam, study the concrete sealing techniques of the special-shaped double wall steel cofferdam and the construction technologies, and propose the solution to solve some problems in the construction. In order to provide references for the construction of similar projects, the pouring construction of pile caps in water is successfully completed without the underwater blasting.
