铁路浸水支挡结构的最不利水位与确定方法

Most Unfavorable Water Level of Submerged Retaining Structure for Railway and Its Determination Method

本文从铁路行业最不利水位的概念和主要作用入手,分析了规范中最不利水位定义的局限性,提出了完善最不利水位定义的建议,构建了以最小偏移率确定浸水支挡结构控制项和最不利水位的通用方法。结合具体的工程实例,演示了确定最不利水位的步骤和过程。

This paper analyzes the concept and main functions of the most unfavorable water level in the railway industry,analyzes the limitations of the definition of the most unfavorable water level in the codes,and then puts forward suggestions on improving this definition.It also establishes a general method for determining the control items and the most unfavorable water level of the submerged retaining structure with the minimum offset rate.At last,the paper demonstrates the steps and processes of determining the most unfavorable water level with specific engineering examples.
