In the heart of Nanjing, China, a team of researchers led by Dr. ZHANG Kunyong from Hohai University has made a significant breakthrough in predicting soil deformation caused by the installation of large-section pipe curtain box culverts. Their work, published in the journal *Yantu gongcheng xuebao* (translated as *Rock and Soil Engineering*), offers a novel approach to calculating surface deformation, which could revolutionize construction practices in the energy sector and beyond.
The team’s research focuses on the complex interplay of forces during the jacking process of large-section pipe curtain box culverts. These structures are crucial for various infrastructure projects, including those in the energy sector, where they facilitate the safe and efficient transport of fluids and gases. However, the installation process can significantly impact the surrounding soil and environment, leading to deformation and potential construction challenges.
Dr. ZHANG and his colleagues, including LI Danyang, ZHANG Meng, and SHEN Xiaorui, have developed a method to calculate surface deformation by considering the combined effects of front propulsion, friction, and soil loss. They built upon classical theoretical solutions, such as the Mindlin solution and the revised Sagaseta formula, to create a comprehensive mechanical model for soils under the jacking process.
“The key innovation here is our ability to superimpose the deformations caused by each influencing factor,” explained Dr. ZHANG. “This allows us to predict the overall deformation more accurately and consider a variety of construction factors and three-dimensional soil deformations.”
The researchers validated their theoretical solution through engineering examples, demonstrating its practical applicability. Their findings provide a robust tool for predicting deformation in real-world construction scenarios, which can help engineers mitigate potential issues and optimize construction processes.
For the energy sector, this research holds significant commercial implications. Accurate deformation prediction can lead to more efficient project planning, reduced construction risks, and minimized environmental impact. As Dr. LI Danyang noted, “Our method can help ensure the safe and stable installation of culverts, which is crucial for the energy sector’s infrastructure projects.”
The team’s work not only advances the field of geotechnical engineering but also sets a new standard for construction practices in the energy sector. By providing a reliable tool for deformation prediction, they pave the way for more sustainable and efficient infrastructure development.
As the energy sector continues to expand and evolve, the demand for accurate and efficient construction methods will only grow. The research conducted by Dr. ZHANG and his team offers a timely and valuable contribution to this ongoing effort, highlighting the importance of interdisciplinary collaboration and innovative problem-solving in addressing real-world challenges.
