摘　　要：大规模海工耐久混凝土在国内应用很少,各种影响因素对其影响作用不甚明了,通过正交设计的方法研究各影响因素对耐久性的影响,对指导配合比设计和施工过程质量控制具有积极的意义。A large-sized construction of durable concrete is seldom applied in China, so it is not understood well what influences are made on durable concrete by all influencing factors. The research on influences on durability is made by adopting orthogonal design method,which has positive significance to guiding design of fitting ratio and control of construction quality.

关 键 词：海工耐久混凝土 正交设计 耐久性 配合比设计 施工质量 桥梁
