Nanjing Study: New Soil Consolidation Method Boosts Energy Infrastructure Stability

In the heart of China, a groundbreaking study led by Chao Han from State Grid Jiangsu Electric Power Co., Ltd. Construction Company in Nanjing is set to revolutionize how we handle soft soils, particularly in the energy sector. The research, published in ‘Frontiers in Built Environment’ (which translates to ‘Frontiers in Civil Engineering’) delves into the intricate world of soil consolidation, offering a novel approach that could significantly impact large-scale construction projects, including those in the energy sector.

The study focuses on the double drainage consolidation of annular soil piles, a technique that addresses the challenge of high-water-content silt—a common issue in ecological dredging and engineering construction. Traditional consolidation methods often fall short when dealing with the unique deformation and loading conditions of these soil piles. Han’s research introduces a new calculation model that accounts for radial deformation, providing a more accurate and practical solution.

“The preparation of central pressurized annular soil pile is mainly based on the principle of soil drainage and consolidation,” Han explains. “But the deformation direction and external force loading mode are different from the classical consolidation theory.” This insight led Han to develop a finite element solution that considers radial deformation, a critical factor often overlooked in conventional methods.

The implications of this research are vast, particularly for the energy sector. Soft soils pose significant challenges for the construction of power plants, transmission lines, and other critical infrastructure. By improving the consolidation process, Han’s method could enhance the stability and longevity of these structures, reducing maintenance costs and potential failures. “The influence of the related factors in the preparation process of annular soil pile, including the initial water content, external load size, internal and external diameter size and nonlinear compression index, on the development of consolidation degree and the growth of internal diameter in the preparation process is studied,” Han elaborates, highlighting the comprehensive nature of the study.

This research not only advances our understanding of soil mechanics but also paves the way for more efficient and effective construction practices. As the energy sector continues to expand and evolve, the ability to manage and utilize soft soils more effectively will be crucial. Han’s work, published in ‘Frontiers in Built Environment’, offers a promising path forward, one that could shape the future of construction in the energy sector and beyond.
