【摘要】：依托阿尔及利亚矿石码头项目,提出一种新型的双排圆筒结构,采用Abaqus有限元分析软件对其波峰作用下的结构拟静力非线性响应进行数值分析。对于两排圆筒间采用简支板连接及采用混凝土厚板连接的两种方案,后者更可以保持变形的协调性,基顶应力的最大值也更小,且连接板的强度要求不难满足,但其造价较高。简支板方案中,对于连接板缝里填充柔性材料与不填充柔性材料两种情况,前者的填料土压呈现上大下小的线性分布,后者则相反,且连接板传递的荷载会占较大的比例,基顶应力也更大。
[Abstract]:Based on the Algeria ore wharf project, a new type of double-row cylindrical structure is proposed. The pseudostatic nonlinear response of the structure under the action of the wave peak is numerically analyzed by using Abaqus finite element analysis software. For the two rows of cylinders, the simply supported plate connection and the concrete thick plate connection are adopted. The latter can maintain the compatibility of deformation, the maximum stress of the base top is also smaller, and the strength requirements of the connecting plate are not difficult to meet, but its cost is higher. For the case of flexible material filled in jointed plate and non-filled flexible material, the soil pressure of the former shows a linear distribution of large and low, while the latter is the opposite, and the load transmitted by the connection plate will account for a large proportion. The stress at the base top is also greater.

【正文快照】： 对于外侧为挡浪墙,内侧兼作码头靠船的直立式结构,在波浪较大的情况下,由于不存在背后回填土,为满足结构的稳定性,其宽度必然较大。但是,结构的宽度受限于当地的施工水平和施工条件,这一点对海外项目来说尤为明显。阿尔及利亚矿石码头工程采用双排圆筒结构,使结构的稳定性满足，
