摘要
桩基与钢围堰共同受力的前提是钢围堰下沉到最大冲刷线以下一定深度,封底混凝土与基岩或较好的地质层紧密粘接,这样钢围堰下沉就存在一定难度。文章以安庆桥钢围堰下沉为例,重点介绍此类工程的施工要点和过程控制。
The steel cofferdam bear load together with the foundation pile only when it can sink to a certain depth beneath the maximum erosion line, but when bottom concrete gets well with bedrock or the fine stratum, it will be hard for the cofferdam to sink further.Taking cofferdam sinking of Anqing Road-Bridge, the essentials and process control in this kind of engineering are introduced.
