新疆新和县北山防洪项目1号洪沟设计洪水分析计算

Design Flood Analysis and Calculation for No. 1 Flood Ditch of Beishan Flood Control Project in Xinhe County, Xinjiang

摘要: 本文聚焦于新疆新和县北山防洪项目1号洪沟项目的设计洪水计算，在无实测洪水数据的情况下，系统用洪峰模数法、推理公式法、经验公式法和调蓄经验单位线法等多种水文分析方法进行设计洪水计算。详细阐述各方法的原理、优缺点，并对计算结果进行深入对比分析。研究表明，推理公式法在小流域设计洪水计算中展现出较高的可靠性和安全性，适合作为无实测资料地区的推荐方法，为类似地区的防洪工程设计提供了科学依据。

Abstract: This paper focuses on the design flood calculation for the No. 1 flood ditch of the Beishan Flood Control Project in Xinhe County, Xinjiang. In the absence of measured flood data, multiple hydrological analysis methods were systematically used, including the peak modulus method, rational formula method, empirical formula method, and storage-based empirical unit hydrograph method. The principles, advantages, and disadvantages of each method are elaborated, and the calculation results are compared and analyzed in depth. The study shows that the rational formula method exhibits high reliability and safety in design flood calculation for small watersheds, making it suitable as a recommended method for areas lacking measured data, providing a scientific basis for flood control project design in similar regions.
