以工程应用为原则 ,研究沉入式大直径圆筒码头的分类及相应的设计理论与计算方法。根据大直径圆筒码头的工作原理 ,提出了大直径圆筒桩墙式码头的新概念 ,以及将沉入式大直径圆筒码头划分为大直径圆筒重力式码头和大直径圆筒桩墙式码头两种结构类型。建立了大直径圆筒桩墙式码头的稳定性计算方法。对于大直径圆筒重力式码头的稳定性验算 ,建议采用重力式码头的计算思路 ,但要合理考虑筒内外土体对结构稳定性的作用。通过数值计算 ,研究了结构特征参数对大直径圆筒桩墙式码头稳定性的影响。
Based on the principle of engineering application, this paper studies the classification of submersible large-diameter cylindrical quay and the corresponding design theory and calculation method. According to the working principle of the large-diameter cylinder wharf, a new concept of the large-diameter cylinder wharf wharf is proposed, and the submerged large-diameter cylinder wharf is divided into a large diameter cylinder gravity wharf and a large diameter cylinder wall Wharf two types of structures. The stability calculation method of large diameter cylindrical pile wall wharf is established. For the checking of the stability of the large-diameter cylinder gravity wharf, the calculation method of the gravity wharf is suggested, but the effect of the soil inside and outside the cylinder on the structural stability should be considered reasonably. Through the numerical calculation, the influence of structural characteristic parameters on the stability of large diameter cylindrical pile wall wharf is studied.
