根据富春江船闸扩建改造工程,从设计角度对中高水头枢纽船闸改扩建工程围堰的导流标准、总体布置及结构设计进行重点研究。在兼顾防洪、发电、河道变化等需求前提下研究确定围堰枯水期防洪等级,结合船闸水工建筑物布置优化调整围堰总体布置方案,并根据坝下围堰不同区段提出不同结构形式的过水围堰,为类似的中高水头枢纽船闸改扩建工程围堰设计提出新设计理念和思路,为多样性的围堰工程增加新特点。
According to the expansion project of Fuchun River Ship Lock, the diversion standard, overall arrangement and structure design of cofferdam for the expansion and expansion of the middle and high water level headlocks are studied from the perspective of design. Based on the needs of flood control, power generation and river courses, the cofferdam flood prevention grade is researched and determined, and the cofferdam layout is optimized and adjusted according to the layout of the ship’s hydraulic structures. According to the different structural forms of cofferdam under different conditions Water cofferdam, put forward new design concepts and ideas for the design of cofferdam of similar middle and high headlocks expansion project, and add new features for the diversified cofferdam project.
