摘　　要：大藤峡水利枢纽工程二期围堰拆除需在深水下进行拆除施工,拆除最大水深达19.60 m,围堰拆除难度较大。本文结合模型试验成果,提出合理的二期围堰拆除设计方案,在满足泄流能力及发电的前提下,结合挡水条件,分区拆除施工,尽量减少水下拆除量,加快施工进度,为同类工程提供了良好的参考。The demolition of the cofferdam of the second phase of the Datengxia Water Conservancy Project needs to be carried out under deep water,and the maximum water depth of the demolition is 19.60m,so it is difficult to remove the cofferdam.Based on the model test results,this paper proposes a reasonable demolition design scheme for the second phase cofferdam.Under the premise of satisfying the discharge capacity and power generation,combined with the water retaining conditions,the demolition construction is carried out in different areas to minimize the amount of underwater demolition and speed up the construction progress,which provides a good reference for similar projects.
