摘　　要：坡地分类是研究坡地的基础,不同分类是有不同的实用意义,一般的分类主要是基于地质研究或径流研究等。该文主要研究坡面地区建构筑物受洪水影响时的沿程水位变化,以便优化防洪规划设计,在此基础上,对坡面进行分类和概化,并根据概化模型推导出坡面地区建构筑物沿程水位计算公式。计算结果表明,随着建构筑物尺寸的加长,在不利条件下,水位远高于自然情况。提出的水位计算公式,适用于坡面地区特别是大型坡面地区上的建构筑物沿程水位估算。Slope classification is the foundation for studying slopes.Different classifications have different meanings,and general classifications are mainly based on geological research or runoff research.This article mainly studies the changes in water level along the slope in order to optimize flood control planning and design.Based on this,the slope is classified and generalized,and a formula for calculating the water level along the slope is derived based on the generalized model.The results show that the water level is much higher than the natural situation under unfavorable conditions,with the lengthening of distance.The formula is applicable to the estimation of water levels on sloped areas,especially large sloped areas.
