摘　　要：针对目前大型工程泄水闸预应力锚索设计方法和控制标准不统一的问题,本文根据《水工混凝土结构设计规范》(DL/T 5057—2009)对弧形闸门预应力混凝土闸墩的颈部提出的抗裂验算的控制标准,以某工程为例,采用工程中成熟的U型主锚索布置方式,探索泄水闸预应力锚索的设计与研究,并提出了一套以三维有限元分析为基础的设计方法和思路,对类似工程问题提供借鉴。Aiming at the problems from the non-unification between the design of the pre-stressed anchor cable for large sluice and its control standards,the control standards for the anti-cracking checking made on the neck of the radial gate pre-stressed concrete pier are put forward herein in accordance with the Design Specification for Hydraulic Concrete Structures （DL/T 5057-2009）.By taking an actual project as a case,the design and research of the pre-stressed anchor cable for sluice are explored by adopting the mature U layout mode of the main anchor cable usually used in the project concerned.In this study,a set of 3-D finite element analysis based design methods and concepts are put forward; which has a certain reference for solving the similar engineering problems.
