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...

Influence of system parameters on thermal performance of energy slab installed in underground structures
Abstract: The energy slab is a ground coupled heat exchanger equipped in building slab structures, which has a similar layout to the horizontal ground heat exchanger (GHEX). As the energy slab is generally installed at the shallow depth, its thermal performance is notably inferior to the conventional vertical GHEXs. This is because the energy slab cannot use the high thermal capacity of a deep...
