Dam safety intelligent monitoring and pre-warning system based on full life circle and method thereof

Abstract

The invention relates to a dam safety intelligent monitoring and pre-warning system based on full life circle and a method thereof, and belongs to the intelligent monitoring and pre-warning field of hydraulic and hydro-power engineering safety. By taking the full life circle of a high arch dam as a main line, a three-dimensional digital technology as a foundation and a building information model as a core, a full dam information model (DIM) including an overall three-dimensional structure of high arch dam concrete and foundation and construction process information are established, and an intelligent technology is applied by an intelligent high arch dam construction information platform for quality management and dynamic analysis control based on DIM development, so that the high arch dam construction such as application of essential data in the design period, full-process monitoring in the construction period and all-around monitoring and safety assessment and pre-warning analysis evaluation in the operation and management period of the high arch dam is realized, refine management and control on the high arch dam are realized, a foundation is provided for the safety management of the high arch dam, and safe operation in the whole life circle of the high arch dam is guaranteed.

Description

technical field [0001] The invention belongs to the field of dam safety monitoring in water conservancy and hydropower projects, and relates to a dam safety intelligent monitoring and early warning system and method based on the entire life cycle of engineering structures. Background technique [0002] With the implementation of the country's western development strategy and the strategy of power transmission from west to east, my country's hydropower projects have developed very rapidly. Many representative large-scale and super-large hydropower projects have been launched one after another. Concrete high arch dams have become one of the main dam types of large-scale water conservancy projects. First, there are many high and extra-high arch dams under construction and to be built. In recent years, with the successive construction of 300m-level ultra-high arch dams such as Xiluodu and Jinping I, as well as a number of 200m-level and above and Xiaowan 300m-level ultra-high arc...

Problems solved by technology

Among them, the "Real-time Monitoring System for Rolling Quality of Core Rockfill Dam Filling" uses GPS high-precision positioning technology and implementation tracking technology to realize the monitoring of raw material transportation and automatic control of the water addition process, as well as the dam rolling track and number of passes. Real-time tracking, accurate and real-time control of the construction process of rockfill dams, representing a relatively high level in China, but due to relatively single system functions and lack of effective integration with project management systems and other business management systems, the above-mentioned The application of the method has not been continuously developed and popularized. There have been no similar reports in the same period in the real-time monitoring of the whole process of concrete high arch dams, especially in the process control of concrete construction and temperature control of high arch dams.

[0005] It can be seen that, from the perspective of the overall construction and operation life cycle of high arch dam projects, there is still a lack of a comprehensive and comprehensive modern management method.
