摘要
文中针对国外某电站弧门推力超过2500 t,在执行国外标准的前提下,采用U形预应力闸墩设计方案,并对闸墩进行了有限元数值仿真模拟,成功地解决了薄闸墩、大推力的关键性技术难题,在工程安全性和经济性两方面有一定价值,对我国今后开展类似国外项目具有指导意义。
In this paper,U-shaped prestressed gate pier design scheme is adopted for a foreign power station whose arc gate thrust exceeds 2500 t under the premise of implementing foreign standards.The finite element numerical simulation of gate pier is carried out,which successfully solves the key technical problems of thin gate pier and high thrust.It has certain value in engineering safety and economic economy,and has guiding significance for similar foreign projects in China in the future.
