摘　　要：岷江大桥主桥有部分桥墩处于河床内,常年水深为2.5m左右,枯水期也不会干涸,但水位会变低。通常在桥梁基础施工中,当桥梁墩、台基础位于地表水位以下时,一般采用围堰施工技术。该文根据项目实际情况及所处的地理环境,总体考虑施工方案和技术要求,对实施工艺技术和注意事项等方面进行了详细梳理总结,旨在为类似项目实施提供参考。实践证明,该项目的工艺技术应用是成功的。Part of the piers of the Minjiang River Bridge are located in the riverbed, where the water is largely 2.5m deep and never dries up even in the drought period throughout the year, but the water level usually reduces. Generally, when the bridge pier and abutment foundation are below the surface water level, the construction technology of cofferdam is applied. Based on the actual situation and geological environment of the project, this paper elab-orates and summarizes the construction techniques and noteworthy tips in light of the overall construction plan and technical requirements, aiming to provide some references for similar programs. And the techniques and technologies applied in this project are proved to be successful through practice.
