摘要
Abstract
Jiusongshan auxiliary dam is the longest dam in Miyun Reservoir and also the one with the largest leakage.Given the long-term high water level operation of Miyun Reservoir,a detailed analysis of its seepage and deformation is crucial for timely detection of potential hazards and ensuring project safety.This paper evaluates the operational status of the longest period Jiusongshan auxiliary dam using safety monitoring data from 1991-1999 and the second longest period high water level operation from 2018-2023.By analyzing the seepage and surface deformation of the representative dam sections 1#and 2#,the operational status of Jiusongshan auxiliary dam was evaluated,providing a basis for assessing the overall operational condition of the Miyun Reservoir project.The analysis focused on the seepage flow and sur-face deformation of the representative dam sections,providing a basis for assessing the overall operating condition of the Miyun Reservoir project.关键词
