底梁式全直桩高桩码头水平力作用下的特性分析

摘要

Because the whole stiffness of the structure of all-vertical-piled wharf is less, the capacity for resisting the horizontal loads is poor. To improve the shortage, the all-vertical-piled and mudsill wharf structure is proposed. This paper uses finite element method and selects the nonlinearity reinforced concrete structure as a calculating model, analyzes and compares the characteristics of deformation and stress of the all-vertical-piled with or without mudsill respectively under the horizontal force. The results show that owing to the setup of mudsill in the all-vertical-piled wharf, the overall stiffness of the structure has increased; thereby, its capacity to resist horizontal loads has improved greatly.%全直桩高桩板梁式码头结构整体刚度较小,抵抗水平荷载的能力较差,为改善其不足,提出了底梁式全直桩高桩板梁码头结构型式.文中运用有限元方法,并选用非线性钢筋混凝土结构为计算模型,分别对有无底梁的全直桩高桩码头结构在水平力作用下结构的变形及内力特征进行了计算分析比较.结果表明:全直桩高桩码头结构由于设置了底梁后,结构整体刚度增大,其抗水平能力大幅度提高.
