摘　　要：为适应三峡175 m蓄水后复杂地质、水文和施工环境条件下码头建设需要,提出钢护筒与钢筋混凝土联合受力的内河大水差架空直立式结构,并建立考虑钢护筒和钢筋混凝土联合受力的数值分析模型。通过与现场试验测试数据对比验证模型可靠性,进而提出基于最不利单元搜索的单位荷载组合法,并利用该法对复杂工况条件的该类码头力学特性进行探讨。通过大量变得参数的数值计算,得到大水差码头复杂荷载环境下的力学特性、薄弱环节及其优化设计方案。The steel-tube-concrete combined bearing inland overhead vertical wharf was built up adapting to the complex geologic-hydrologic conditions and construction environment during 175 m water storage of the Three Gorges.Meanwhile,a numerical model was established under consideration of steel tube-R.C.concrete combined bearing.By comparing test data with numerical results,we verified the reliability of the model and further proposed the element’s unit load combination,which was used to investigate the mechanical performance of this kind of wharf under complicated conditions.Moreover,the weak part and reinforcement were proposed.
