New Risk Assessment Method Enhances Safety in Karst Tunnel Construction

Sudden water inrush incidents pose a significant threat to karst tunnel construction, a challenge that has long plagued engineers and construction professionals. In a groundbreaking study published in ‘Tehnički Vjesnik’, Xin Zhang from the Institute of Karst Geology at the Chinese Academy of Geological Sciences and China University of Geosciences has developed a new risk assessment method to tackle this pressing issue.

Zhang’s research focuses on multiple karst tunnels currently under construction in Guangxi, where geological conditions can lead to catastrophic water inrush events. The study identifies seven critical factors that influence the risk of water inrush, including rock mass quality, the angle of rock mass dip, and surrounding rock strength, among others. By employing a combined weighting-TOPSIS method, Zhang aims to provide a systematic approach to evaluating these risks.

“The safety of tunnel construction is paramount, and our method allows for a more nuanced understanding of the geological factors that can lead to water inrush,” Zhang explained. “By quantifying these risks, we can better prepare for and mitigate potential hazards.”

The innovative approach combines subjective weights derived from a hierarchical analysis with objective weights calculated through an entropy method. This dual strategy leads to a more comprehensive risk assessment, allowing construction teams to make informed decisions. The validation of this method through advanced geological drilling indicates its reliability and potential for widespread application.

The implications of this research extend beyond the academic realm. For construction companies, implementing this risk assessment model could dramatically reduce the likelihood of water-related incidents, which can lead to costly delays and safety hazards. As Zhang notes, “A proactive approach to risk assessment not only enhances safety but also improves project timelines and budget management.”

With the construction industry increasingly prioritizing safety and efficiency, Zhang’s findings could shape future developments in tunnel engineering and risk management practices. The ability to predict and mitigate water inrush risks not only safeguards workers but also contributes to the overall viability of tunnel projects.

As this research gains traction, it has the potential to influence practices globally, driving the construction sector toward more advanced and scientifically grounded methodologies. For those in the industry, staying informed about such innovations is crucial for maintaining a competitive edge.
