研究目的:结合锦州至赤峰铁路线勘测的实践,综合分析沿线流域内的诸多因素,探索出一套计算小流域地区暴雨径流验证的方法。研究结果:结合本地区河流水系、水文、气象等自然特征,采用4种水文计算方法,得出不同公式计算流量的结果,经比较分析,锦州至赤峰铁路沿线,选用地方公式法计算小流域暴雨径流是适合的。 Research purposes: Combining with the practice of railway survey from Jinzhou to Chifeng, we comprehensively analyze many factors in the basin along the river and explore a set of methods to calculate stormwater runoff in small watershed. Results: Based on the natural characteristics of rivers, hydrology and meteorology in the area, four hydrological methods were used to calculate the results of different formulas. After comparative analysis, the local formula method was used to calculate the rainstorm in small watershed Runoff is suitable.
