Abstract_Chinese:\r针对浮体-张力筋腱非线性耦合系统，采用时域分析方法对局部系泊失效下的张力腿平台进行动力响应分析，重点研究两根筋腱失效时筋腱失效位置、波浪载荷参数与平台各自由度动力响应的关系．结果表明：局部系泊失效对平台横荡、纵荡、艏摇自由度的动力响应影响远小于横摇、纵摇、垂荡自由度；失效位置与平台动力响应关系密切，失效筋腱位置越集中，平台响应越大，反之亦然；筋腱失效后平台在不同波浪载荷参数下的运动特性及顶端张力表现各异．垂荡瞬态阶段响应对波高和波周期敏感性较强，垂荡稳态阶段响应对浪向、波高和波周期敏感性较强；纵摇(横摇)瞬态和稳态阶段响应对浪向、波高和波周期敏感性均较强；波浪载荷参数对筋腱顶端张力的影响较小．\r

Abstract_English:\rIn terms of the nonlinear coupling effect of a tension leg platform(TLP) hull and tendons，the dynamic response of a TLP with multiple broken tendons was analyzed using a time-domain method．The relationship among tendon failure positions，wave force parameters，and dynamic responses of six degrees of freedom was then investigated．It was found that with multiple broken tendons，the dynamic responses of sway，surge and yaw were far smaller than those of roll，pitch and heave．The tendon failure positions had close correlations with the TLP dynamic responses．The more centralized the tendon failure positions were，the higher the TLP responses were，and vice versa．As wave parameters varied，the TLP performance varied across different motion characteristics and at peak tension．The transient heave response was sensitive to wave height and wave period，while its steady-state response was sensitive to wave direction，height，period．However，the transient and steady-state responses in pitch and roll were also sensitive to wave direction，height，and period．The wave force parameters had small impact at top tension of tendon.\r
