In the past few decades, the number of tunnels constructed next to an existing tunnel has
been gradually increasing in order to accommodate infrastructure needs in congested urban …

The primary means of transportation for various substances including water, oil and natural
gas are the nation's pipelines. From the geotechnical perspective, one of the prime reasons …

This paper examines the effect that tunnel size, depth and volume loss have on greenfield
soil displacements above tunnels in sandy ground. The results of a series of plane-strain …

Tunnelling in the dense urban areas frequently results in over-crossing or bypassing the
existing tunnels. It is obvious that the over-crossing tunnelling will adversely affect and even …

This paper proposed an analytical solution to investigate the response of an existing tunnel
induced by new tunnel excavation underneath. A Timoshenko beam lying on a Kerr …

Understanding the pipe-soil interaction is critical for the design and safety assessment of
buried pipelines subjected to large differential ground motion. Laboratory model tests were …

In recent years, with the rapid increase of urban subway lines, crossing engineering has
become another complex problem of modern tunnel construction techniques, and especially …

Tunnel construction is vital for the development of urban infrastructure systems throughout
the world. An understanding of tunnelling-induced displacements is needed to evaluate the …

Seismic faulting is extremely detrimental to buried pipelines owing to bending moments and
axial forces generated by the soil–pipe interaction. Pipe responses to ground rupture are …

Tunnel driving inevitably induces changes in stress and deformation in the ground, which
could cause ultimate and serviceability problems to an adjacent tunnel. The effects of …
