In recent years, as a new type of water-retaining structure, the Air Shield Dam has become a research hotspot and industry focus in water conservancy engineering owing to its unique advantages.

I. Core Technical Research Directions

The core research of Air Shield Dam mainly focuses on three aspects: durability of airbag materials, automatic control system, and dam structure optimization.

• • The development of high-strength composite airbags has significantly improved the anti-aging and anti-fatigue performance of the equipment, with a service life of more than 30 years.
• • The application of intelligent sensing and remote monitoring systems has realized precise control of dam lifting and lowering, as well as fault early warning.

II. Hot Application Topics

The widely discussed application scenarios of Air Shield Dams include:

• • Urban River Ecological Management: Featuring low water head and landscape compatibility, it is the preferred solution for water interception and flow regulation.
• • Rural Water System Connectivity Projects: Low cost and fast construction effectively resolve conflicts between farmland irrigation, flood control and drainage.
• • Ice Flood and Ice Melt Regulation: In northern regions, Air Shield Dams flexibly adjust water levels to reduce ice flood disasters.

III. Development Trends

In the future, Air Shield Dam technology will evolve toward intelligent operation and maintenance, green low-carbon materials and modular design. It will promote the transformation of water conservancy projects from "hard engineering" to "flexible governance", becoming the preferred technology for the regulation of small and medium rivers.
