抓住机遇减免三门峡水库对陕西库区的危害(上)

Mitigate harms of Sanmenxia reservoir by making use of Xiaolangdi reservoir

利用小浪底水库有 72 .5亿 m3淤沙库容的有利时机 ,基本可以单独完成下游综合利用调节任务 ,从而使三门峡水库的综合利用任务改变为 :根据“确保西安”的原则 ,以库区排沙、防洪、防凌为主 ;发电的运用以不影响潼关水位为前提条件 ,力争潼关水位能尽快恢复到接近三门峡建库前水平。

Since the Xiaolangdi reservoir has a sediment capacity of 7.25 billion m 3 and can individually fulfill the regulation functions of d/s comprehensive utilization, the Sanmenxia reservoir's functions can be changed as follows. 1) Reservoir sediment ejection, flood control and ice-jam prevention are its main functions provided that Xi'an's safety is ensured; 2) Generation operation should be under the precondition of no effect on the water level at Tongguan and strive to resume the level to that before construction of the Sanmenxia reservoir.
