温度效应对全直桩现浇梁板高桩码头结构的影响

Thermal effect on vertical piled and cast-in-situ deck wharf

针对温度效应对全直桩现浇梁板高桩码头的影响问题,在75、150、200、300 m等4个不同长度的结构段上增加温度效应后对内力的影响进行对比和论述,采用国际通用有限元软件进行三维空间计算,得出国内环境下适当增长结构段长度可对桩基、纵横梁的弯矩、剪力和轴力值均有一定程度的降低。

Aiming at the thermal effect on the vertical piled and cast-in-situ deck wharf, comparing inner force results due to the different length（75,150,200,300 m） of structure segment with additional thermal action based on 3D dimension calculation by international finite element software,the results reveal that the internal forces such as bending moment,shear force,axial force of pile foundation and deck elements can be significant reduced by the appropriate growth of segment length plus the effect of thermal actions.
