摘要
Abstract
Under the"dual-carbon"strategy and the green transformation of infrastructure,in order to solve the prob-lems of large tool wear and low energy utilization rate in the shield tunneling in gravel-stratum geology,and achieve the balanced optimization of economic and environmental benefits of large-diameter shield tunnel projects,the large-diameter shield tunneling project for the river-crossing section of the Qinwang Tunnel in Fuyang District,Hangzhou City was taken as the research object.By collecting and analyzing the data of shield tunneling projects in complex geological conditions containing pebbles,combining with literature review and on-site investigation,a stratum classification method suitable for shield tunneling in gravel-stratum geology was established by technologies such as data preprocessing,KNN algorithm,and random forest algorithm,and an economic index library for large-diameter composite slurry balance shields under complex geological conditions was constructed.These outcomes can supplement and improve the current shield pricing system,providing a scientific basis and practical reference for the economic analysis and cost control of similar projects.关键词
