利用流域影响因子推算山坡坡度的研究

Study on Calculation of Mountain Slope Using by Basin Contributory Factor

用模糊聚类分析方法将流域样本分为两类,然后用回归分析理论分别对各类样本进行分析,建立起山坡平均坡度与流域影响因子之间的回归方程。把所得结果用于现有桥梁的水文验算中,可以节约验算者的大量时间,而且按此结果计算出的洪峰流量与按传统方法计算的洪峰流量接近且偏于安全。

The paper divides the basin sample into two categories by the analytics of the confused poly category, then the result is used in the hydrologic check of the existing bridge so as to save the time for checker. At the same time, the peak flow calculated by the result is close to the peak flow calculated by the traditional method and is safer.
