Abstract

In the pursuit of sustainable development, the environmental impacts of geotechnical engineering are often neglected. The utilization of geosynthetic-reinforced soil (GRS) and ecological slope protection technology presents promising and eco-friendly alternatives, paving the way for a cleaner future. In this study, the temporal and spatial distribution of the carbon coefficient (CC) and embodied energy coefficient (EEC) are characterized through data analysis. Subsequently, the impact of spatial factors on the total embodied carbon (TEC) is considered. Finally, the carbon sequestration effect of vegetation through photosynthesis is quantified to examine the long-term environmental impact of the selected design options. The findings suggest that embodied carbon (EC) is preferable as an indicator for environmental impact assessment. The GRS technology can effectively mitigate approximately one-third of the environmental impacts compared to conventional methods. Furthermore, when combined with vegetation, GRS technology can achieve net-zero emissions approximately 30 years after the construction of the ecological retaining structure. Although many factors are not considered in this study, the results may inform initial decisions to realize more sustainable infrastructure.

期刊介绍： The range of products and their applications has expanded rapidly over the last decade with geotextiles and geomembranes being specified world wide. This rapid growth is paralleled by a virtual explosion of technology. Current reference books and even manufacturers' sponsored publications tend to date very quickly and the need for a vehicle to bring together and discuss the growing body of technology now available has become evident. Geotextiles and Geomembranes fills this need and provides a forum for the dissemination of information amongst research workers, designers, users and manufacturers. By providing a growing fund of information the journal increases general awareness, prompts further research and assists in the establishment of international codes and regulations.
