| 摘 要： | 二滩拱坝泄洪中孔工作弧门支承结构具有承受水头高、水推力大、高速水流震动影响及检修困难等特点。为改善其应力状态，确保泄洪消能安全，设计采用预应力锚固技术。本文简要介绍工作弧门支承结构和预应力锚索设计的成果，并运用三维有限元法对其应力分布规律进行了研究，为设计提供依据。

| Abstract: | Service radial gates at middle level outlets on Ertan arch dam featrues high head bearing,high water thrust bearing,vibrating effecting by high speed flow and difficult maintenace. Pre-stressed anchor tech-nology is used to improve the stress condition for safe performance of flood release and energy dissipation. The paper briefly introduces the design and research of bearing structures and pre -stressed anchor line for the service radial gates and analyzes the stress distribution pattern by using three-diminsional finite element method to provide design considerations. |
