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 …

Buried water pipelines are vulnerable to fail or break due to excessive loading or ground
displacements. Accurate evaluation of pipe performance and serviceability relies on the …

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 …

New developments in both the theory and the practice of tunnelling are covered in the
lecture. The important relationship between tunnelling and geotechnics is highlighted, and …

As an increasing number of metro tunnels are being constructed in congested urban areas,
it is inevitable that new tunnels are being constructed in close proximity to existing tunnels …

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 …

Tunnelling provides a robust solution to a variety of engineering challenges. It is a complex
process, which requires a firm understanding of the ground conditions as well as the …

This paper presents a case study of protecting existing tunnels during the construction of a
new cut-and-cover tunnel above in Nanjing, China. Various construction measures …

The paper examines the problem of tunneling beneath buried pipelines and the relationship
between soil strains and pipeline bending behavior. Data are presented from centrifuge …

Determination and monitoring of tunneling induced ground displacement is an important
component in tunneling design and construction. In recent years several technologies for …
