【摘要】 根据影响悬河稳定性的因素,确定了构造、堤基、河道地质地貌3类共14个评价因子,建立了模糊评判模型,选取96个模糊计算评价点,对黄河山东段悬河稳定性进行了综合评价,并对悬河稳定性进行了分区。通过对各河段可能出现的失稳或决口险点及其可能造成的危害性进行分析和预测,初步确定了需要重点防御的10处地质险段。更多还原

【Abstract】 It determines altogether 14 assessment factors in 3 categories of tectonic structure,embankment foundation,geology and geomorphy of the river channel,builds a fuzzy assessment model,conducts integrated assessment on the stability of the elevated Yellow River in Shandong section by selecting 96 points of fuzzy calculation and assessment and zones the stability of the elevated river according to the factors that influence to the stability of the elevated river.It preliminarily determines 10 vulnerable sections for special defense through analysis and prediction on unstable or critical spots for dike breaks that possibly happened and possibly caused damages at each section.更多还原
