Abstract: In recent years, the early built aqueduct structure has gradually entered the disease-prone period, and the safe operation and management of the aqueduct structure are facing serious challenges.In order to effectively control the working state of the existed aqueduct, taking the existed aqueduct in Dongfengqu irrigation area of Sichuan Province as an research object, and combining with the existing engineering structure safety monitoring technology, we systematically analyzed and studied the selection of the monitoring content of the aqueduct structure, the layout of the measuring points, the structural safety early warning and emergency response, the structural safety assessment and decision support, and finally a set of monitoring-warning-decision-making aqueduct supervision and management system was formed.The research results have certain reference values for establishing structural safety monitoring system of existed aqueducts in other irrigation areas in China.
