大圆筒结构由于具有材料用量省 ,结构尺寸大 ,受力条件好的优点 ,在港口工程中被推广应用 ,目前 ,已有的工程实例以有基床的大圆筒结构居多 ,沉入式的沉管结构工程实例极少。文章通过在潮间带就地边预制边下沉的大直径沉管结构的工程实例 ,介绍结构设计应注意的问题和施工工艺措施。
Large cylinder structure due to the amount of material used in the province, the structure of large size, the advantages of good stress conditions, is being applied in port engineering, at present, the existing engineering examples to have a large base of large cylindrical structure, sinking sink Very few examples of pipe structure engineering. The paper introduces the structural design problems and construction process measures through the engineering examples of the large-diameter immersed pipe structures pre-fabricated on the ground side in the intertidal zone.
