有限元法在趸船码头系锚排架优化设计中的应用

内河码头水位差较大,趸船系泊一般需要分层系缆.由于码头后方陆域条件及工程条件所限,趸船系缆在无法采用常规锚墩的情况下,通常采用独立桩或排架结构形式.针对重庆主城一趸船码头系锚排架的设计,采用有限元方法对趸船系锚排架结构进行计算.结果表明,排架结构与独立桩系锚结构相比,具有受力条件好、造价经济的突出优势.同时,设计中增设排架结构联系梁的切角可以降低排架受力后联系梁与桩柱连接处的应力集中程度,提高排架结构的承栽能力,可为类似排架结构的设计提供参考.

Application of finite element method in optimization design of anchoring bent on pontoon wharves

Since the water head is relatively large at inland rive wharves,the pontoon wharve mooring generally needs layered bond cables.The pontoon wharves bond cables usually use separate piles or bent structure if they fail to use conventional anchor pier due to constraints of land area conditions behind the wharves as well as the engineering conditions.For the design of anchoring bent at Chongqing main city-pontoon wharves,the finite element method is used to calculate the structure of anchoring bent.The results ...
