摘　　要：通过分析大型涵洞式渡槽施工具有混凝土外观质量及整体性要求高、单体工程量大、大体积薄壁结构易产生裂缝等技术难点，在涵洞式渡槽施工过程中着重从渡槽混凝土仓位设置、钢筋的制作加工及安装、模板的选择及其施工、混凝土施工等角度进行分析，提出相应需采取的质量控制措施以及施工过程中应注意的技术要点。同时针对混凝土施工过程中容易出现的质量问题的原因进行了具体分析，进而提出了相应的措施以防止质量问题的产生。By analyzing the technical difficulties of high requirements of concrete appearance quality and integrity, single large quantities and large volume of thin-walled structure with cracks, as well as the concrete aqueduct position, the construction and installation of steel reinforce- ment, template selection and the concrete construction in the culvert aqueduct construction process, we proposed the measures should be taken to control quality and the technical points that should be noted in the construction process. We made specific analysis of the reasons why quality problems occurred in the concrete construction process, and then put forward the corresponding measures to prevent the quality problems.
