In the high-stakes world of hydropower, where the stability of dam slopes can mean the difference between megawatts of clean energy and catastrophic failure, a groundbreaking study is shedding new light on the behavior of problematic slopes. Lili Chen, a researcher from the School of Architecture and Civil Engineering at Xi’an University of Science and Technology, has delved into the intricate mechanics of a creep-sliding and tension-fracturing slope, offering insights that could reshape how we approach slope stability in hydropower projects.
Chen’s study, published in *Geomatics, Natural Hazards & Risk* (which translates to *Geomatics, Natural Hazards & Risk* in English), focuses on a near-dam slope at a hydropower station, where the deformation and stability of such slopes are paramount for safety during construction and operation. By analyzing the topography, geomorphology, and rock mass features, Chen and her team have uncovered the spatial distribution characteristics of key structural planes, providing a detailed understanding of the slope’s behavior.
One of the most compelling aspects of this research is the use of graded loading creep tests to determine the creep mechanical properties of the area’s sandy slate. “This testing verified the applicability of the constitutive model and provided reliable creep parameters for numerical simulation,” Chen explains. This step is crucial for accurate modeling and prediction of slope behavior, which can significantly impact the design and maintenance of hydropower infrastructure.
The study also combines field monitoring with three-dimensional numerical simulation to reveal the spatio-temporal evolution characteristics of the fault-dominated deformation slope. This integrated approach allows for a more comprehensive understanding of how faults and weak planes influence slope stability. “By considering the main faults’ spatial combination and the weak plane effect, we were able to explore the creep-sliding and tension-fracturing deformation mechanism in greater detail,” Chen adds.
The implications of this research are substantial for the energy sector. Understanding the deformation mechanisms of such slopes can lead to more informed decision-making in the design and construction of hydropower projects, ultimately enhancing safety and reducing the risk of costly failures. “Our findings provide theoretical support for evaluating the stability of steep and high slopes of hydropower stations,” Chen notes, highlighting the practical applications of the study.
As the energy sector continues to invest in hydropower as a key component of the renewable energy mix, the insights from Chen’s research become increasingly valuable. By offering a deeper understanding of slope deformation mechanisms, this study paves the way for more robust and reliable hydropower infrastructure, ensuring the continued growth and stability of this vital energy source.
In a field where precision and reliability are paramount, Chen’s work stands out as a beacon of innovation and practical application. As the energy sector grapples with the challenges of climate change and the need for sustainable energy solutions, research like this will be instrumental in shaping the future of hydropower and ensuring its role in a cleaner, more resilient energy landscape.
