Review of research progress on the analysis and treatment of shield tunneling debris
As an important method of tunnel construction,shield method is widely used in urban,mountain tunnel and other engineering construction.Shield debris as an important part of tunnel construction waste,if stacked for a long time,it will cause great harm to the surrounding ecological environment.Therefore,the research and disposal of shield debris is of great practical significance.This paper analyzes the traditional shield debris particle analysis method,shield debris analysis based on digital technology,and the disposal and utilization of shield debris from three aspects.Specifically,the current situation of screening method and laser particle size meter method was enumerated,and then the image acquisition and particle image a-nalysis of particles were elaborated,and finally based on the environmental problems caused by debris and the support of na-tional policies,combined with the current status quo of debris utilization,the reuse mode of debris was summarized in order to quickly analyze the debris and make resource utilization.Our study will provide a reference for the subsequent research of debris treatment technology.
