| 摘 要： | 结合紫坪铺水利枢纽工程的实际情况，采用三维有限元方法对该工程发电引水系统取消伸缩节的可行性进行了研究。计算结果表明，主厂房上游永久分缝处以一段垫层管代替常规伸缩节，结构位移和应力完全可以满足使用要求，从而达到了取消伸缩节、节省工程投资的目的。

| Abstract: | By integrating with the actual situation of Zipingpu Water Conservancy Project, feasibility study on replacing expansion joint in the hydropower project water diversion system is carried out by using three dimensional FEM. The results show that replacing conventional expansion joint by penstocks with cushion layer at the upper stream permanent joint of the main workshop can meet the requirements of structural displacement and stress. Thus, it is feasible to replace expansion joint thus to save the project cost. |
