Application of Artificial Neural Network for Prediction of Surface Settlement During Shield TBM
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...

Classification of surface settlement of stacked twin tunnels by machine-learning
Abstract: To ensure the safe operation of tunnel boring machines (TBMs) in urban areas, surface settlements should be monitored at several levels such as the alert, action, and alarm level, to prevent any damage to nearby infrastructures. In this study, the random forest (RF) machine learning model was implemented to predict the surface settlement levels using a database collected from a Hong Kong subway...

FEM based Estimation of EDZ under TBM induced Vibration
Abstract: Excavation-induced vibration is one of the main concerns in urban underground construction. The vibration during excavation can be the cause of ground disturbance, or even damage the soil structure which may have negative effect to the stability of structures nearby, and to the surrounding ground. To overcome these situations, the application of mechanical excavation using tunnel boring machine...

Numerical Study of Waterproofing Membrane Considering Contact Behavior
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,...
