| 摘 要： | 南水北调中线天津干线工程钢筋混凝土箱涵结构具有断面尺寸大、浇筑方量大、质量要求等级高等特点。浇筑成型后的箱涵应力应变如何分布,对其运行安全、工程耐久性、结构性能具有重大影响。三维数值仿真技术的研究分析则找出了其变化规律,指导了施工。

| Abstract: | Reinforced concrete box culvert structure of South-to-North water diversion midline Tianjin trunk project is characterized by larger cross section area, larger pouting capacity, high quality requirement grade, etc. Box culvert stress distribution after pouting and shaping has great influence on safe operation, engineering durability and structural performance. Its change rules can be discovered by study and analysis by three-dimensional numerical simulation technique, thereby guiding construction. |
