| 摘 要： | 作为海洋平台的基础部分,桶形基础不仅承受海洋平台结构及自身重量等竖向荷载的长期作用,而且往往还遭受波浪等所产生的水平荷载及力矩等其它荷载分量的作用.因此,确定软基上桶形基础在竖向荷载(V)、水平荷载(H)和力矩(M)等共同作用下的承载特性,建立其在复合加载模式下的破坏包络面,并进而依此评价海洋平台基础及地基的稳定性,是...

| Abstract: | Bucket foundation is a new-type offshore foundation applicable especially for marginal field oil extraction,which is usually subjected to the simultaneous actions of both gravity and other environmental loads.Gravity loads act vertically while environmental loads induced by wave,wind and current are imposed laterally with both horizontal load and moment on the foundation.The responses of suction caisson foundation subjected to such a type of combined loads are therefore of great importance for the design an... |
