This book focuses on the research of deformation, particularly the transverse deformation of shield tunnels. First, the theoretical analysis focusing on structural mechanics was introduced, and then a series of full-scale model tests were carried out to replicate the structural deformation under gradually increasing loading. The test program covered most tunnel structure types utilized in Shanghai, and the deformation mechanisms of different tunnel structures were separately analyzed and summarized. Besides, tunnels with reinforcement measures were also tested to verify the effects of reinforcement. Based on the research results, controlling standards for structural safety of tunnels were proposed, and several measures for the treatment of deformation were introduced with four application cases in Shanghai. From this book, readers will learn the deformation mechanisms of shield tunnel structures and corresponding treatment measures, which could help the readers solve relevant issues and strengthen the risk awareness of structure safety at the same time.
