【摘要】 本文对某工程坝身泄水建筑物的预应力闸墩进行三维有限元计算,对比分析闸墩上游预留竖井式和胶结式内锚头两种锚固形式的应力分布特点;经过综合比较,推荐最终采用的锚固形式,为闸墩结构设计提供依据,对工程设计和施工具有参考价值。更多还原

【Abstract】 Based on practice of prestressed pier design of certain project,the 3D FEM computation of the prestressed pier in the flood discharge buildings of some double curvature arch dam is carried out.The stress distribution has been compared between the two forms of anchorage: obligating silo in upward side of the pier and cementing the inside anchor.The computation has shown the stress distribution of the two anchorage forms before and after applying the prestress,which is helpful to the design and construction of similar projects.The final anchorage form adopted is recommended after synthetical comparison.更多还原
