摘　　要：对水下生产系统防沉板基础在附加额外扭矩或弯矩后承载力及其可靠性进行了分析。在多载荷作用下的基础极限承载力的基础上,分析附加载荷作用下的基础水平和竖向承载能力的衰减。综合考虑H-T-M-V,根据载荷的作用情况,建立结构失效的安全余量方程,并分析联合失效概率。通过算例表明,本文方法是必要的,是符合工程实际的,为综合考虑H-T-M-V的水下生产系统防尘板基础承载力分析提供了一个合理的方法。Considering the additional torque or moment, the bearing capability and reliability of mudmat foundation of subsea production system were analyzed. First based on the bearing capability degradation analysis under mult-loads, the horizontal and vertical bearing capability under additional loads were analyzed. Whereafter the H-T-M-V were integrated, based on the load condition, the safety margin equations were established, and the failure probability are analyzed. Finally by the example it can been seen that the method of this paper coincides with the engineering fact and its necessary. A reasonable method for reliability analysis of mudmat foundation of subsea production system under H-T-M-V was provided
