【摘要】：1950年以来,区域中小型水库、塘坝窖池等水利工程和水土保持工程的建设,地下水超采等人类活动,对永定河官厅山峡水文系列的一致性产生了较大影响。基于新安江-海河模型,对官厅山峡的设计洪水成果进行了修订,经计算,100年一遇频率下,官厅山峡3d设计洪量修订值为2.54×10~8m~3,7d设计洪量修订值3.55×10~8m~3。
[Abstract]:Since 1950, human activities, such as regional small and medium-sized reservoirs, water conservancy projects such as Tangba pit and soil and water conservation projects, and over-exploitation of groundwater, have had a great impact on the consistency of hydrological series in Guanting Gorge of Yongding River. Based on the Xinanjiang-Haihe model, the design flood results of Guanting Gorge are revised. It is calculated that the revised value of design flood volume of Guanting Gorge is 3.55 脳 10 ~ (8) m ~ (3) under the frequency of 100 years, and the revised value of design flood volume is 2.54 脳 10 ~ (8) m ~ (-1) ~ (37) m ~ (-1) 路d ~ (-1).
