| 摘 要： | 依据洮河干流上、中、下游的四个主要控制水文站点的实测月、年径流量资料,运用矩法和Mann-Kendall秩次检验法等方法,研究洮河干流径流的周期性、突变性、相关性等变化规律,揭示洮河干流径流年内年际的演化规律和趋势变化特点。结果表明:洮河干流上、中、下游年内分配多年变化一致,由集中向均匀转变,但变化趋势不显著;自上游向下游不均匀性增强;径流量年际变化大,但总体有逐渐减小的趋势;洮河上游、下游径流年际变化稳定,中游年际变化剧烈。

| Abstract: | Landslide stability is mainly affected by rainfall and human activities.By analyzing the lifting height of groundwater level in rainfall conditions,the link of hydrodynamic pressure in rainfall and after rainfall is established,and the stability of slump-mass under the action of rainfall and seepage is calculated.The landslide stability of three Gorges Reservoir area results show that they are quite consistent with engineering practice when considering the role of rainfall and seepage and the method has a good engineering applicability. |
