不同高程下系缆平台设计的有限元分析

在桩基已完成施工的情况下,采用MIDAS有限元分析的方法,对不同高程下系靠船墩结构的受力特性进行分析,并对影响结构位移及稳定性的主要因素做进一步研究,得出采用MIDAS有限元分析墩式码头结构受力性能是可行的,同时桩基嵌固点对靠船墩整体稳定性影响较大,而增加自身质量或改变自身刚度对靠船墩整体稳定性影响较小的结论。另外,工程上可采用人工抛石等方式提高工程桩基嵌固点,增加结构整体稳定性。

Finite element analysis of cable platform design for different elevation

Under the condition that the pile foundation has been completed,we apply the MIDAS finite element analysis method to analyze the static characteristics of dolphin pier of different heights,and further research on the main factors which influence the stability of structure displacement.It is concluded that the MIDAS finite element analysis of dolphin pier wharf structure performance is feasible,and build-in pile point to dolphin pier has a greater influence on the overall stability,while increasing its weight or changing its stiffness has a smaller effect on the stability of dolphin piers.Moreover,methods like rock rip-rap can be used in engineering to rise the engineering pile foundation point,which can increase the overall structural stability.
