In the present work, important aspects of time-dependent nonlinear 3D finite element (FE) models for deep tunnel advance by the New Austrian Tunneling Method (NATM), characterized by repeated sequences of excavation, securing, and idle periods, are d

This paper presents a particular tunneling method, the new Austrian tunneling method (NATM), which plays an important role in reducing subsidence of the surface and damage to structures in urban areas. It has a wide range of applications in shallow t

The New Austrian Tunnelling Method (NATM) tunnel design is performed by testing support classes against the geological profile. We propose to replace this manual process with reinforcement learning, a generic framework within the realm of artificial

Due to the fast growth of urban areas worldwide, the demand for tunnels in developed areas is increasing. The design and construction of those tunnels are complex because of their shallow depths and their interaction with existing aboveground and bur

Nowadays, due to the increasing urban environments, increasing the density of surface structures and the lack of space for intra-urban transportation, the need to implement underground structures such as tunnels and subway stations in urban environme

The new Austrian tunnelling method (NATM) and tunnel boring machine (TBM) are methods for excavating underground spaces. The NATM construction method has noise and vibration problems, and excavation using TBM has the disadvantage of high initial cost
