| 摘 要： | 采用ANSYS有限元软件,对排架数、排架间距、桩基直径、承台宽度、岸坡坡度等5种影响因素进行数值分析,并应用单因素敏感性分析方法和灰色关联分析方法分析这5种影响因素对水平撞击力分配系数的敏感性大小。结果表明:排架间距对水平撞击力分配系数的影响最大,其次是桩基直径、排架数、承台宽度,最不敏感的是岸坡坡度。同时为水平荷载均匀分配在各个排架提出合理的建议,使架空直立式码头结构达到安全、经济和适用的目的。

| Abstract: | Through finite element software ANSYS,numerical analysis is carried out on the influence of the amount of bent frames,bent frame spacing,pile diameter,cap width and bank slope gradient.The single factor analysis method and the grey relational sensitivity analysis method are applied to analyze the sensitivity of the impact of the proposed five factors on the distribution coefficients of horizontal impact force.The results show that the bent frame spacing influences the distribution coefficients of horizontal impact force mostly,the followed are pile diameter,the amount of bent frames,cap width,and the least sensitive factor is bank slope gradient.At the same time,reasonable suggestions on horizontal load distribution on each bent frame are proposed in order to guarantee the safety,economy and applicability of the straight-wide pile framework wharf. |
