Abstract
Based on the current research and application status of anti void grouting materials for tunnel secondary lining arch crown,this article analyzes the main factors causing arch crown void,and clarifies the key role of grouting technology and materials in solving arch crown void;This paper discusses the traditional grouting materials,grouting materials with formwork,grouting technology,composition and performance testing of grouting materials,summarizes the progressiveness of grouting materials with formwork and the trend of secondary lining testing,puts forward the compatibility,micro mechanism and long-term durability evaluation between grouting materials with formwork and lining concrete,and puts forward suggestions for further research.关键词
