Urban rail transit has been developed rapidly worldwide due to its significant social and
economic benefits. At the same time, it is also faced with some key technologies to be solved …

Rockburst has perennially posed a formidable challenge to the stability of underground
engineering works, particularly under conditions of deep-seated high stress. This paper …

With the rapid development of metro construction, shield machines inevitably have to
traverse a variety of complex geological conditions, leading to the frequent occurrence of …

Excavation of urban subway tunnels through hard rock can induce strong vibration waves,
particularly in the soil layer and existing building infrastructure. Such vibrations affect the …

Metro (subway) is an advanced public transport infrastructure system in urban areas with
high capacity. The traffic operation of a metro is not affected by other vehicle traffic thanks to …

For the buildings with pile foundations adjacent to or even right above the metro tunnels,
mitigation measures in isolating the metro-induced vibration propagation along the pile …

This study focuses on a problem that has been seriously troubled urban traffic managers: the
impact of underground excavation metros on surface traffic safety during construction. In …

Double-shield TBM is more efficient than shield tunnel construction in hard rock strata. It is
widely used in subway tunnel construction, such as in Qingdao and Chongqing in China …

Constructing tunnels in urban spaces usually uses shield tunneling. Because of numerous
uncertainties related to underground construction, appropriate monitoring systems are …

Excavation of subway tunnels in hard rock generates strong vibration waves that pose
potential risks to the stability of surrounding structures. In this study, the discrete element …
