密云水库潮河主坝高水位运行工况下工程性态分析与评价

Analysis and evaluation of engineering properties of the main dam of the Chaohe River in Miyun Reservoir under high water level operation conditions

密云水库的蓄水量由于南水北调等原因持续增加,高水位运行成为常态,这对潮河主坝的安全运行是一个非常严峻的考验。选用建库以来高水位运行期间,潮河主坝变形、渗流监测等监测资料,运用对比、制表及绘图等方法,分析了潮河主坝在高水位运行工况下工程性态以及可能面临的问题,最后对保证潮河主坝的安全运行提出了合理性建议,以期为今后密云水库的安全运行提供参考。

The storage capacity of Miyun Reservoir continues to increase due to the South-to-North water transfer, and high water level operation has become the norm, which is a very serious test for the safe operation of the main dam of the Chaohe River. Based on the monitoring data of deformation and seepage monitoring of Chaohe main dam during the high water level operation since the construction of the reservoir, this paper analyzes the engineering behavior and possible problems of Chaohe main dam under the high water level operation condition by using the methods of comparison, tabulation and drawing. Finally,reasonable suggestions are put forward to ensure the safe operation of the main dam of Chaohe River, in order to provide reference for the safe operation of Miyun Reservoir in the future.
