摘要:
山洪灾害危险区等级的定量划分是沿河村落山洪灾害分析与评估的重要内容,并能为山洪灾害的预警与防治提供科学依据。本文针对甘泉县洛河沿岸村落,根据不同设计频率下的暴雨特征值进行产汇流计算,给出了20%、5%、1%等3个频率下的设计洪水;利用HEC-RAS计算了不同设计洪峰流量下的水面线,通过对比分析沿河村落的居民宅基高程与3种频率洪峰水位,评价了其防洪能力,进而将危险区等级划分为极高危险区(<5年一遇)、高危险区(5~20年一遇)、危险区(20~100年一遇)和不危险区(>100年一遇)。结果显示,分析评价的56个沿河村落中,极高危险区、高危险区和危险区分别约占3.6%、16.1%和10.7%,且大多分布于干支流交汇口处,而防洪能力较高的不危险区主要位于支流的上游地区。山洪灾害的防治应着重治理干支流交汇口处的区域;根据防洪能力定量划分山洪灾害的危险等级,能够为沿河村落山洪灾害的风险评估及防治提供依据。
Abstract:
The quantitative division of dangerous area is an important content of mountain flood disaster analysis and evaluation in the villages along the river. It can provide a scientific basis for early warning and prevention of flash flood. According to the characteristics of the rainstorm under different design frequency, we calculated the runoff and confluence of the villages along the Luohe River in Ganquan County, and got the design flood under 3 frequencies of 1%, 5% and 20%. Then we calculated the surface line of different flood peak by HEC-RAS software, and compared it with the homestead elevation of residents along the river to determine the flood control capacity. And the dangerous area would be classified into high risk area (<5 year), high risk area (5~20 year), dangerous area (20~100 year) and no danger area (>100 year) according to the size of flood control capacity. The results showed that the highest risk area, the high-risk area and the dangerous area accounted for 3.6%, 16.1% and 10.7% respectively in the 56 villages along the river, most of which were distributed at the intersection of the main stream and the tributary. However, the non-dangerous areas are mainly located in the upper reaches of the tributaries. Therefore, these areas in the intersection of the main stream and the tributary should be emphasized in the prevention and control of mountain torrents. The risk grade of mountain flood disaster can be divided according to the flood control capacity, which can provide the basis for risk assessment and prevention of flood disaster along the river.
