Key technologies and future development trends of intelligent earth–rock dam construction

Abstract

Keywordsartificial intelligence rolled earth-rock dam intelligent detection of gradation building information modeling (BIM) rapid assessment on compaction qualityThe rapid advancement of information technologies, such as cloud computing, internet of things (IoT), and big data, has significantly enhanced the intelligence level in dam construction. Intelligent monitoring systems for dam filling have garnered considerable attention from water conservancy and hydropower engineering units, owing to their capability for refined management and quality control of layered and compartmentalized construction processes. The construction of earth-rock dams has undergone a transformation, shifting from manual management of dam compaction equipment, layer management, and quality control to a comprehensive intelligent approach. This new approach encompasses finegrained control of unit engineering, dam material identification, unmanned driving technology, real-time assessment and monitoring of compaction quality, and early warning forecasting. This article presents a systematic overview of key technologies employed in the intelligent construction process of earth-rock dams. These technologies include the fine decomposition of building information modeling (BIM) models on web platforms, rapid identification of dam material particle size, the application of autonomous driving technology for intelligent dam filling, and real-time monitoring and evaluation of dam compaction characteristics. Additionally, the paper discusses the latest research results in the field, building upon existing technology progress, and concludes by exploring the future development trends of intelligent dam construction. The construction of intelligent earth-rock dams serve as a crucial reference and valuable lessons for the development and construction of high earth-rock dam projects.

Evaluation Study on the Application Effect of Intelligent Construction Technology in the Construction Process

“…At the same time, through the photo series or video frame extraction, the longer construction process is compressed in a shorter time for video playback. (6) In terms of environmental management: installing dust and noise monitoring equipment, real-time monitoring of environmental data, and video-assisted real-time recording; when the value exceeds the standard, it is to carry out early warning and leave a record through intelligent equipment, automatic remote linkage control, and monitoring and management of integrated management. (7) In terms of green construction management: (1) Intelligent water and electricity monitoring and management.…”

“…With the continuous maturation of the new generation of information technologies, such as BIM (Building Information Modeling) [2], Internet of Things [3], 3D printing [4], Big Data, Artificial Intelligence [5], etc., the concept of "intelligent construction" was born. According to Allied Market Research [6], the global intelligent construction market size is expected to grow from $60.7 billion in 2019 to $105.8 billion by 2024, with a compound annual growth rate of approximately 11.7%. In recent years, the scale of China's intelligent construction industry has also shown substantial expansion, exceeding 1 trillion in 2020, accounting for more than 3% of the total output value of the construction industry, as shown in Figure 1.…”
