Method of stability analysis of embedded large-diameter cylinder quay

摘要: 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。

Abstract: The idea that the embedded large-diameter cylinder quay can be divided into two types: the gravity type and the pile wall type, is presented in this paper. The method of the stability analysis is developed for the large diameter cylinder quay of the pile wall type and the method of the stability analysis for the large diameter cylinder quay of the gravity type is also proposed. The effect of the significant parameters on the stability of the large diameter cylinder quay of the piled wall type is investigated through numerical calculation.
