摘　　要：为了获得典型构件在实际服役环境中的荷载水平范围,选取在役的3个码头梁构件设计实例,以横梁、纵梁、轨道梁为研究对象,理论分析出构件在“永久荷载”或“永久荷载＋可变荷载”作用下的荷载水平;另在华南地区选取某高桩码头,进行现场应力测试与分析,得到实际服役环境下的构件荷载水平。通过现场应力测试及典型实例理论分析,确定了码头正常使用条件下钢筋混凝土结构荷载水平范围为0.1~0.47,为开展在役海工结构实际服役状态的荷载模拟试验提供依据,为码头结构设计提供参考。To obtain typical components load level range in practical service environment, by selecting design examples for three marina beam members in service, and taking the beam, stringer and track beam as the research object, we analyze the component load level under the ＂permanent load＂or＂permanent load plus variable load＂. Besides, taking a high-pile wharf in Southern China for case study, we carry out the site stress test and analysis, and obtain the load level in the actual service environment. Based on the site stress testing and theoretical analysis of typical examples, we determin that the load level range for the wharf under normal condition shall be from 0. 1 to 0. 47, which provide the basis for conducting simulation tests in load-service marine structures and provide a reference for the pier design.
