汛期将至，哪些独门绝技确保大坝安全运行？

Core Viewpoint - The article discusses the challenges and advancements in the seismic safety of high dams in China, particularly in the context of increasing extreme weather events and seismic activity in the regions where these dams are located [2][3][5]. Group 1: Seismic Challenges and Standards - High dams in China are primarily located in seismically active regions, necessitating advanced seismic safety measures due to the combination of seismic forces and other loads such as water pressure and temperature changes [2][3]. - The current seismic design standards for dams in China are among the most advanced globally, having been revised post-Wenchuan earthquake to include checks for "maximum credible earthquakes" [3]. Group 2: Research and Innovations - Research led by experts like Professor Jin Feng focuses on the overall safety of river basins to prevent cascading disasters from dam failures, with improvements in monitoring and response mechanisms [3]. - Innovations in materials, such as high-performance concrete and self-healing concrete, are being explored to enhance the durability and safety of high dams [6][7]. Group 3: Intelligent Monitoring Systems - The deployment of intelligent dam systems equipped with thousands of sensors allows for real-time monitoring of stress, deformation, and other critical parameters, enabling rapid safety assessments after seismic events [7][8]. - The concept of "smart dams" is being developed, where dams will have sensing capabilities similar to smart home devices, enhancing their operational safety [8].
