摘要
以一艘200m3抓斗挖泥船定位桩系统为例,通过建立其三桩联合桩-土相互作用模型,在1个抓斗作业周期内对其定位桩系统在极端工况组合载荷下的动力响应进行数值模拟,着重分析主船体的水平位移响应、各桩桩靴承载力的变化规律及其桩周土体的受力特点等,为工程应用提供参考。
The three-spud model of a 200 ma grab dredger based on spud-soil interaction is built. The dynamic response of spuds in one grab-dredging cycle under combined loads in ex- treme conditions is studied by numerical simulation method, and the horizontal displacement response of main hull, the bearing capacity variation of each spud shoe, and the stress charac- teristics soil around the spud, etc. are considered. It provides some references for engineering application.
