Abstract #

This paper discusses the significant risks posed by ignoring the primary stress state in the design of geotechnical structures, particularly in the context of slope stability and highway construction. The study focuses on the mechanisms of slope movements, including sliding and landslides, and how these geohazards can be exacerbated by inadequate geotechnical design. The paper also provides case studies from highway construction projects in Slovakia, where improper consideration of the primary stress state led to severe slope deformations and structural failures.

Technical Relevance #

This document is crucial for geotechnical engineers and infrastructure developers working in complex geological conditions. It highlights the importance of understanding and incorporating primary stress states into the design process to prevent geohazards such as landslides and slope failures. The detailed analysis of real-world projects serves as a valuable lesson in the potential consequences of neglecting this critical aspect of geotechnical engineering.

Target Audience #

The document is intended for geotechnical engineers, civil engineers, project managers, and researchers involved in the design and construction of infrastructure projects, particularly in areas prone to slope instability. It is also relevant for students and academics studying geohazard mitigation and advanced geotechnical design techniques.

Software and Methodology #

The study involves the use of stability analysis software and techniques to assess the impact of primary stress states on slope stability. The methodology includes detailed geological surveys, numerical modeling, and risk assessment procedures to evaluate the stability of slopes during and after construction. The paper emphasizes the need for continuous monitoring and adjustment of the design process based on real-time data from the construction site.

Process Description #

The paper begins with an introduction to the mechanisms of slope movements, including sliding and landslides, and their impact on infrastructure projects. It then details several case studies from highway construction projects in Slovakia, where the failure to account for primary stress states led to significant geotechnical issues. The process description includes the design and implementation of stabilization techniques such as retaining walls and pilot walls, and the challenges faced during the construction process.

Main Findings #

The study concludes that ignoring the primary stress state in geotechnical design can lead to severe geohazards, including large-scale slope failures and infrastructure damage. The case studies highlight the importance of an integrated design approach that considers all geological factors, including primary stress states, to ensure the long-term stability and safety of infrastructure projects. The findings also emphasize the need for thorough geological surveys and continuous monitoring during construction.

Practical Applications #

The insights from this study are directly applicable to the design and construction of highways and other large-scale infrastructure projects in geologically complex areas. Engineers can use the findings to improve their understanding of primary stress states and their impact on slope stability, leading to more robust and reliable designs. The study also serves as a cautionary tale, illustrating the potential consequences of neglecting critical geotechnical factors in the design process.

Limitations and Considerations #

The document acknowledges that while the study provides valuable insights into the impact of primary stress states on slope stability, the findings are based on specific case studies from Slovakia. Engineers should adapt the methodology and conclusions to their specific project conditions and conduct site-specific analyses to ensure accurate and reliable results.

Conclusions #

The paper concludes that the primary stress state is a critical factor in geotechnical design, particularly for projects involving slope stability and highway construction. The study highlights the need for comprehensive geological surveys, accurate modeling, and continuous monitoring to prevent geohazards and ensure the safety and stability of infrastructure projects. The findings underscore the importance of integrating all relevant geological factors into the design process to achieve successful outcomes.
