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 …

Tunnel excavation inevitably induces stress changes in the surrounding soil leading to
significant ground movements and additional stress in nearby pipelines. Most previous …

An analytical solution for the deflection and internal forces of an existing tunnel because of
tunneling underneath is presented. The existing tunnel is modeled as a Timoshenko beam …

This paper focuses on the effect of tunneling-induced ground deformation on the response
of jointed cast iron and ductile iron pipelines that (i) cross the settlement profile …

The process of tunneling is associated with ground movements which may lead to stressing
of nearby existing buried infrastructure, and potentially poses a risk of damage. The need for …

地层沉陷致埋地HDPE 管道事故频发, 主要原因之一是地层沉陷过程中所诱发的管道附加应力和
变形剧增, 从而导致管道破坏. 已有研究成果大多集中于固定尺寸沉陷区域管道与周围土体力学 …

Pipeline–tunnel interaction has attracted increasing research attention recently. Previous
studies focused mainly on tunneling-induced deformation in continuous pipelines. In this …

The Volume of the settlement trough is essential for estimating the settlement caused by
tunneling. Generally, the volume of the settlement trough was recognized as a constant …

Failure of buried high-density polyethylene (HDPE) pipes caused by land subsidence is
often encountered in the engineering practice. The main reason is the additional stress and …

Available analytical methodologies for the stress analysis of buried pipelines against large
permanent ground displacements (PGDs) apply only to straight pipeline segments. Hence, a …
