利用走道板作为水池顶端不动铰支承，在设计中被广泛采用。它可改善水池壁板的受力条件，减少池壁厚度并大大减少钢筋用量。《给水排水工程结构设计规范》（ＧＢＪ６９─８４）对走道板的刚度条件给出明确规定。然而在执行ＧＢＪ６９─８４的规定过程中发现规范的规定过于严格。本文结合工程中成功的作法，对规范存在的缺陷重新对走道权的刚度条件从理论上加以推导，所得结果可为工程实际应用。本文给出设计中全部所需公式及表格，实用性强。
The use of a walkway plate as an immovable hinged support for the pool top is widely used in the design. It can improve the force conditions of the pool wall, reduce the thickness of the pool and greatly reduce the amount of steel. The “Code for the Structural Design of Water Supply and Drainage Works” (GBJ69-84) gives clear rules on the stiffness conditions of the walkway plates. However, the regulations found in the implementation of the provisions of GBJ69-84 were too strict. In this paper, combining the successful practices in the project, the defects of the specification are re-evaluated theoretically on the stiffness conditions of the walkway weights. The results obtained can be applied to the project. This article gives all the required formulas and tables in the design, and it has strong practicality.
