| 摘 要： | 针对大水位差全直桩框架码头多层系缆层以及相对于传统高桩码头存在纵横撑的两大特点，应用sap2000对结构多种水平撞击力工况进行了数值分析。通过计算各排架基底剪力与撞击力的比值，得到了各工况下排架的水平撞击力分配系数。分析结果表明：撞击力位置越低，荷载分配越集中，分配系数越大；纵撑增大了结构的纵向刚度，改变了荷载传递途径，有利于水平撞击力的均匀分配；同时，横撑有利于撞击力的横向传递，但不利于撞击力的纵向分配。

| Abstract: | A numerical analysis by sap2000 to the structure in many horizontal impact force cases is made against All-vertical-piled wharf two traits with great height of water that is multi-layered moors and the presence of lateral and lengthways braces which are not shown in traditional high-piled wharf.Horizontal impact force's partition coefficient in each load case is obtained through calculating ratio between framed bent's shear force of bottom with impact force,it is concluded that the lower impact force's loca... |
