Abstract: Surface settlement induced by shield TBM tunnel excavation in shallow soft ground can threaten the stability of adjacent structures in urban areas. Controlling the ground surface settlements occurred during tunneling is one of the key issues for tunneling engineers. Numerous researches for the prediction of surface settlement have been attempted along with analytical, empirical and/or numerical...
Abstract: An waterproofing membrane has a relatively higher initial strength, faster construction time and higher waterproofing performance than the conventional sprayed concrete linings. Waterproofing membrane mainly consists of polymers and its supporting potential is from the adhesion at the interface and tensile strength which is distinct from the conventional method such as the shotcrete. However,...

Abstract: Some risks such as machine settlement, jamming, damage of cutters and others are frequently encountered due to the uncertainties of geological and operational factors during subsea shield TBM tunnelling. This paper, thus, focused on the risk assessment of shield TBM tunnelling in adverse ground conditions. Particularly, the correlation between shield TBM settlement and its advance rate was...
