摘　　要：介绍载荷抗力系数设计(Load and Resistance Factor Design,LRFD)方法的背景和原理。在此基础上,以某深水半潜式钻井平台的舵机基座强度分析为例,基于挪威船级社海洋结构物设计规范和经典力学理论,展示LRFD方法在海洋结构物局部结构强度分析中的实际应用,表明该方法的特点。This paper introduces the background and principles of Load and Resistance Factor Design(LRFD)method.The strength analysis of the steering gear base of a deepwater semi-submersible drilling platform is taken as the example to demonstrate the application and characteristics of LRFD method in the local structural strength analysis of offshore structures based on both the design specifications of DNV GL Classification Society and the classical mechanical theories.

关 键 词：结构设计 强度分析 载荷抗力系数设计(LRFD)方法 海洋结构物
