Multi-layer lining design: a new framework for tunnel lining design

As the single layer sprayed concrete lined (SCL) primary lining design gradually becomes the “norm”, design of multi-layer lining (MLL) that comprises a permanent primary lining layer and the following lining layers becomes a real challenge. Dr. Jiang Su discusses this emerging topic from engineering fundamentals, and suggests the necessity of upskilling a new breed of “hybrid tunnel engineers”.
