regional earthcrust stability
Examples
- Through analysing the topography and landforms , rocks , geological structure and regional crust stability , etc , the geological condition of project on moving and settling construction land in nanan village of baihe township , sichuan jiuzhaigou county , status assesment , forcasting assessment and comprehensive regional assessment about the geological hazard of this site are made and also the conclusion and suggestion are given
摘要通过对四川省九寨沟县白河乡南岸村搬迁安置建设用地的地形地貌、地层岩性、地质构造与区域地壳稳定性等工程地质条件的分析，对该场地的地质灾害危险性做出了现状评估、预测评估及综合分区评估；并提出了结论与建议。 - ( 4 ) the dike breach risk of the south bank is relative higher in wandering reaches . ( 5 ) the dike breach risk of the north bank is higher than the south bank in winding reaches . simultaneously , the evaluation results manifest that the evaluation indexes system established from the locomotion of incoming water and sediment load , the regional crustal stability , the evolvement of river regime and the stability of river dikes , can reflect the actual situation of hang river in the lower yellow river more fully
评价结果同时表明,从水沙运动、区域地壳稳定性、河势演变和堤防稳定性4个方面建立评价指标体系,能够更加全面的反映黄河下游悬河的实际情况;运用多层次模糊综合评判法能够较好地解决影响因素众多、作用机制复杂的悬河决溢风险问题;运用gis技术强大的空间分析功能,使黄河下游悬河不同空间位置的决溢风险得到了量化,可以客观地反映黄河下游河道不同空间位置决溢风险的差别,对于指导防洪和河道治理的实践具有重要的现实意义。 - Based on analysis of hang river ' s actuality in the lower yellow river and researches related with evaluation of dike breach risk , it is put forward that the influencing factors of hang river dike beach risk in the lower yellow river should involve 4 aspects , the locomotion of incoming water and sediment load , the regional crustal stability , the evolvement of river regime and the stability of river dikes . the evaluation indexes system of hang river dike breach risk and uniform synthetic model are established from the 4 aspects . with the support of gis technology , the evaluation indexes system and the model of multi - hierarchical fuzzy synthetic judgment are applied to estimating the dike beach risk of hang river in the lower yellow river under different flood conditions
在对黄河下游悬河现状、决溢风险评价有关研究进行分析的基础上,本文提出黄河下游悬河决溢风险的影响因素应当包含水沙运动、区域地壳稳定性、河势演变和堤防稳定性4个方面,并从这4个方面建立了黄河下游悬河决溢风险评价的指标体系和统一的综合评价模型;在gis技术的支持下,运用评价指标体系和多层次模糊综合评判模型,对不同洪水情景下黄河下游悬河的决溢风险状况进行了评价。
