Learn from the lessons of the Sayano-Shushenskaya Hydroelectric Power Station accident in Russia and further strengthen the safety supervision and management of hydropower stations.
Since the start of construction in 1993, the Three Gorges Project has seen the birth of new technologies, new processes, and new patents every year. According to incomplete statistics, among the scientific and technological achievements of the Three Gorges Project, it has won 18 National Science and Technology Progress Awards, over 200 provincial and ministerial-level Science and Technology Progress Awards, applied for more than 700 patents, and established over 100 engineering quality and technical standards that exceed national and ministerial standards.
Zhang Zhihui, a postdoctoral researcher at the China Three Gorges Corporation Research Station and an associate researcher at the Institute for the History of Natural Science of the Chinese Academy of Sciences, was invited to write an article titled "Three Gorges Project: Creating a New Height in International Water Conservancy and Hydropower Technology," published in China Economic Weekly.
On July 21, 2010, the Three Gorges Dam had opened nine deep flood discharge holes and two drift discharge holes for flood discharge.

The Three Gorges Project is a major national engineering project approved by the National People's Congress. From its design proposal to repeated scientific demonstrations before officially starting construction, it embodies the care and support from the Party and government for this project. The construction began on December 14, 1994, and entered initial operation in October 2006; it is currently the largest water conservancy hub project in the world.
From its inception with excavation of high slopes for ship locks to unit manufacturing, installation debugging, and operational management, the Three Gorges Project has faced various anticipated and unanticipated challenges. Ultimately, scientists overcame numerous technical difficulties achieving over a hundred 'world records.' Since construction began in 1993, new technologies, processes, patents have emerged every year. According to incomplete statistics among its scientific achievements are: winning 18 National Science and Technology Progress Awards; over 200 provincial-level awards; applying for more than700 patents; establishing over100 engineering quality standards exceeding national standards.
In fact, since the1950s generations of scientific experts have begun research efforts around the Three Gorges Project. Major topics proposed by experts such as key equipment for ship lifts have been included in national 'Seventh Five-Year,' 'Eighth Five-Year,' even 'Ninth Five-Year' research efforts. Over40 thousand builders of this project along with thousands of engineers from research institutes across China have persistently contributed to advancing research on this project.
The application of scientific achievements from the Three Gorges Project profoundly reflects China's current level of water conservancy science and technology—especially showcasing local scientists' independent innovations in fields like engineering construction,electromechanical equipment development,and ecological protection. In2011,the dam was recognized as an international milestone concrete dam project.In2016,the project received FIDIC's Century Major Civil Engineering Project Award.
In April2018,during his inspection visit totheThreeGorgesProject,Xi Jinping pointed out that it is a crucial national asset created through hard work by laborers who achieved self-reliance; he felt very inspired after seeing it.The successful completionand operationof this project has turned generationsof Chinese people's dreamsof developingand utilizingThreeGorge resources into reality,making it an important symbolof China's development since reformand opening up.This exemplifies how our socialist system can concentrate resources on major tasks effectively;it showcasesthe wisdomand creativityofChinese people;it representsthe increasingly prosperousstrengtheningofChinese nation.
