The quest to answer the longstanding question of how safe is safe enough has led to an
evolution of design philosophies. The traditional philosophy has been based on ensuring …

A resilient system should have the ability to mitigate the disruption caused by unfavorable
environment and to rapidly recover to an acceptable performance level. In this paper, a …

A field case of operated shield tunnel disrupted by unexpected extreme surcharge in
Shanghai is reported in this paper. The deformational responses of segmental lining, in …

Cross diaphragm (CRD) method divides the tunnel into multiple pilot tunnels to reduce the
span of a single excavation, which is beneficial to reduce the disturbance of excavation …

The operation and maintenance of metro systems play a crucial role in urban development,
with a focus on ensuring the serviceability and safety of metro tunnels. Accurate evaluation …

Nowadays, with increasing urbanization and population of cities, the amount of internal
transportations enlarged. To facilitate these movements, need for subway tunnels has been …

This paper focuses on the ground settlement induced by the construction of a curved shield
tunnel. Ground loss and construction loadings are the two factors causing ground …

Prediction of ground responses is important for improving performance of tunneling. This
study proposes a novel reinforcement learning (RL) based optimizer with the integration of …

In heavily urbanised areas, the construction of tunnels underneath existing ones is
unavoidable and much caution has to be exercised in both design and construction so as …

During the initial design phases of complex multi-disciplinary systems such as urban
tunnelling, the appraisal of different design alternatives can ensure optimal designs in terms …
