摘要
Abstract
Miyun Reservoir is a large-scale water conservancy hub project that combines flood control,irrigation,water supply,and power generation.As a reservoir for the South-to-North water diversion proj-ect,it plays a critical role in water regulation and storage,and is crucial for ensuring the capital's water security.However,with the increase in water from the south,the continuous high water level operation of Miyun Reservoir presents a significant challenge to the safe operation of its main and auxiliary dams.Uti-lizing PS-InSAR technology to capture deformation data of the dam body and surrounding areas of Miyun Reservoir,and conducting deformation monitoring analysis,is crucial for understanding the engineering behavior and potential issues of the main and auxiliary dams under high water conditions.The results in-dicate that the deformation data from PS-InSAR align closely with manual observations,with prominent subsidence occurring on the reservoir's southwest and south sides.The vertical deformations of the three dams exhibited a slight downward trend as the reservoir's water level gradually rose.This experiment of-fers significant reference value for the application of PS-InSAR in dam deformation monitoring.关键词
