【摘要】：依托阿爾及利亞礦石碼頭項(xiàng)目,提出一種新型的雙排圓筒結(jié)構(gòu),采用Abaqus有限元分析軟件對(duì)其波峰作用下的結(jié)構(gòu)擬靜力非線性響應(yīng)進(jìn)行數(shù)值分析。對(duì)于兩排圓筒間采用簡(jiǎn)支板連接及采用混凝土厚板連接的兩種方案,后者更可以保持變形的協(xié)調(diào)性,基頂應(yīng)力的最大值也更小,且連接板的強(qiáng)度要求不難滿足,但其造價(jià)較高。簡(jiǎn)支板方案中,對(duì)于連接板縫里填充柔性材料與不填充柔性材料兩種情況,前者的填料土壓呈現(xiàn)上大下小的線性分布,后者則相反,且連接板傳遞的荷載會(huì)占較大的比例,基頂應(yīng)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.
