中文摘要: |
在松桃县地质灾害危险性评价中,将层次分析模型(AHP)引入信息量模型,选取地层、坡度、坡向、斜坡结构等8评价因子,分别对松桃县滑坡和崩塌两种主要灾种进行危险性评价,并将评价结果按就高不就低原则叠加,实现了区域性的地质灾害危险性评价,并提出地势平缓区的解决思路,有效避免了常规性信息模量评价中出现夸大地形平缓区域地质灾害危险性等级的不合理结果。最终评价精度为80.3%,表明评价结果较好,可为相似区域的危险性评价提供参考。 |
英文摘要: |
The analytic hierarchy process is introduced into the information quantity model in the risk assessment of geological hazards in Songtao countyAnd eight factors including stratum,slope,aspect,slope structure,etc,are selected to evaluate the risk of landslide and collapse in Songtao countyThe evaluation results are superimposed according to the principle of actual situation,and the regional geological hazard assessment is realizedBy putting forward the solution idea of the flat terrain area,the unreasonable result of exaggerating the risk level of geological disasters in the flat terrain area in the conventional information modulus evaluation is effectively avoidedThe final evaluation accuracy was 803%,indicating that the evaluation results were good,which can provide reference for risk assessment of similar areas |
