摘要
考虑桩土联合作用 ,采用三维有限元技术和解析法相结合的方法 ,对东深供水改造工程钢筋混凝土矩形渡槽下部支承结构 (排架和桩基础 ) ,在动、静荷载作用下的受力性能进行了分析 ,并论证了其稳定性能。分析结果表明 ,渡槽支承结构应力条件较好 ,变形量不大 ,满足设计要求 ;在渡槽线路拐弯的地方 ,可加大纵向约束 ,以提高渡槽结构的抗震能力 ,增强整体结构的稳定性。
By considering the interaction between piles and soil, and with combining three dimension finite element technology and analytical method, the mechanical properties of support structure for reinforced concrete rectangular flume in Dong Shen water supply project under static and dynamic loads are analyzed. The stability of the support structure is also analyzed. The results indicate that stress conditions are suitable, deformation values are small, and the design demands are met. Longitudinal restrain at the bend point of the flume should be strengthened to improve earthquake resistance of the flume and to guarantee stability of the whole Structure.
