Design of Waterfront Platform Based on Finite Element Method

摘要:

采用 ROBOT 对亲水平台进行数值模拟分析，验证了 ROBOT 对实际工程计算的适用性。通过较为完整的荷载组合计算分析，研究表明：采用ROBOT数值模拟方法分析高桩亲水平台结构受力性能是可行的，计算结果真实可靠，能够用于实际工程设计；亲水平台最大正弯矩和负弯矩都在船舶撞击力产生的横梁上；亲水平台桩基轴力最大出现在第二排排架第6排桩；桩基弯矩第1～4排桩基弯矩值小，第5和第6排桩基弯矩较大。

Abstract:

The numerical simulation of the waterfront platform is carried out by using ROBOT to verify the applicability of ROBOT to practical engineering calculation. Through a relatively complete load combination calculation and analysis, the research shows that it is feasible to analyze the mechanical performance of the high pile waterfront platform structure by using the ROBOT numerical simulation method, and the calculation results are true and reliable, which can be used in the actual engineering design. The maximum positive and negative bending moments of the waterfront platform are on the crossbeam generated by the ship collision force. The maximum axial force of the pile foundation of the waterfront platform appears in the sixth row pile of the second bent frame. The bending moment of pile foundation in rows 1 to 4 is small, and in rows 5 and 6 is large.
