预应力坞式闸室设计

Design of prestressed dock-type lock chamber

为推广预应力技术在船闸工程中的运用,结合颍上船闸工程的具体应用,采用三维数值仿真分析方法,分析预应力坞式闸室结构的抗裂性能,论述相对于钢筋混凝土闸室结构在经济技术上的优劣性,并提出相应的改进方案。分析结果表明,预应力坞式闸室结构在结构的受力性能、耐久性及经济性等方面均具有一定的优越性。

For the promotion of prestressed technology in lock engineering application, combining the specific application of the Yingshang lock, using three dimensional numerical simulation method, the crack resistance of prestressed dock-type lock chamber was detailed analyzed, the technical and economic advantages and disadvantages were discussed compared with the reinforced concrete lock chamber, and the corresponding improvements were also proposed. The results were shown that the prestressed dock-type lock chamber structure had certain advantages in the structure stress performance, durability and economy.
