| 摘 要： | 木浪河拱坝加高工程为拱坝加高培厚成折线型重力坝,坝体加高幅度大、结构受力复杂.采用有限元分析软件ADINA的非线性接触功能模拟新老坝体的接触关系,对新老坝体结构在各种工况下的应力变形状况进行仿真分析,计算结果表明：在正常蓄水位工况下,加高培厚后的坝体能够较好地整体工作,新老坝体接触面没有脱开,但有较大范围的粘结滑移;新... |

| Abstract: | The Mulang River arch dam is heightened to be a gravity dam with a broken line dam axis,being raised by a large margin with a complex structure and stress state.The nonlinear contact function of FEM software ADINA was adopted to simulate the contact between the old and new dams.The stress and deformation were analyzed in various conditions.The results show that under the normal pool level,there is no gap between the old and new dams while a large range of the interface sliding,the difference in deformation ... |
