| 摘 要： | 为了适应当前的海洋开发需求,海洋工程结构物的大型化已成为必然发展趋势,这使得原有海工建造施工场地的滑道处于临界承载状态,给安全生产带来了巨大隐患。本文针对典型滑道结构,采用有限元参数化建模技术(ANSYS Parametric Design Language,ANSYSAPDL)模拟上部载荷滑块在滑道板上的灵活布置,对滑道强度储备进行分析。研究表明:设计载荷下,滑道板的强度储备较滑道桩体及滑道桩侧土小,滑道强度的控制因素为滑道板强度;改变上部载荷滑块的位置,探索不同位置处滑道极限承载力,提高施工建造过程中滑道利用率。

Analysis of Slipway Strength Safety Reserve of Large Marine Engineering Building Venue |

| Abstract: | With the needs of rapid ocean development,large scale of marine engineering structures has been an inevitable development tendency.This makes the slipways of the original construction site a critical load state and brings a huge hidden danger to the safety production.According to the structure of typical slipway,the slipway strength reserve is analyzed by simulating the flexible arrangement of the upper load slide block on the slipway slab using the finite element parametric modeling technique (ANSYS-APDL).The results show that within the designed load,the strength reserve of the slipway slab is smaller than those of the slide pile and the soil surrounding the pile,indi-cating that the strength of the slipway slab is the factor controlling the slipway strength.To improve the utilization rate of the slipway during the construction,the ul-timate bearing capacities of the slipway at different positions are studied by changing the position of the upper load slide block. |
