Study on the Applicability of Resource Utilization of Tunnel Excavation Waste as Building Materials for Long and Large Tunnels
Through the investigation and rapid evaluation of the lithology of tunnel mucking,this study assessed its potential and feasibility as a building material.The research included the analysis of physical and chemical properties such as mineral composition,mechanical properties,and harmful substance content of the mucking,as well as the durability evaluation of the aggregate.The results show that through lithological investigation and applicability evaluation,it is possible to clarify the technical path of resource utilization,establish an applicability evaluation system for the utilization of tunnel mucking building materials,and define the detection frequency of control indicators.Tunnel mucking can be effectively transformed into various building materials such as aggregate and roadbed filler,achieving resource recycling and environmental protection.In addition,this study proposed a comparison of the crushing value of aggregate detected by standard method and immersion method,which can be used to monitor the quality and production level of mucking,providing theoretical support and practical guidance for practical engineering applications.In conclusion,the utilization of mucking building materials helps to reduce the environmental impact of tunnel construction,reduce construction costs,and promote sustainable development.
