Surface settlement (SS) resulting from tunnel excavation operations is a critical concern in
tunnel engineering due to its potential impact on adjacent structures. This review …

The stability of the middle soil pillar (MSP) is considered to be a crucial factor in ensuring the
safety during the construction of asymmetric parallel tunnels. In this paper, both …

The unprecedented rate of metro construction has led to a highly complex network of metro
lines. Tunnels are being overlapped to an ever-increasing degree. This paper investigates …

Recent research has shown that in a parallel twin-tunnel arrangement, the 2nd tunnel
generates greater settlement than the 1st tunnel as the soil between the two tunnels softens …

In this paper, twin tunnelling-induced surface settlements in drained granular soils were
studied using 1 g physical models. A mechanical device was developed to achieve the …

In most modern cities, public transportation demands are being addressed by constructing
subways. The construction of tunnels, especially in weak and shallow subsurface strata, may …

This paper presents a study on the mechanical response characteristics of supporting
structure of closely spaced super large span twin tunnels based on the field monitoring. The …

Geogrid-reinforced piled embankments (GRPEs) provide an economical and effective way
to construct highways and railways on soft soil foundations. This paper proposed a new …

The stability discrimination method of surrounding rock in vertical shaft construction and the
safety technology of shaft construction under the geological condition of a super-thick crush …

Tunnel construction is becoming necessary as cities continue to grow, particularly in
crowded locations. Thus, the majority of tunneling projects include creating two parallel …
