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 …

With the expansion of underground space networks, new tunnels especially large-diameter
shields under-crossing existing tunnels have been commonly practiced. To obtain a better …

Due to the repaid development of underground space in big cities, increasing excavation
pits is being constructed or planned in a close proximity to existing metro tunnels in dense …

Adjacent excavations may have adverse impacts on the existing tunnels. Due to the
increasing demand for building excavations in close proximity to existing metro tunnels …

A method is presented for estimating the maximum bending moment for continuous (or
rigidly jointed) pipelines affected by tunnel-induced ground movement. The estimation can …

Due to the increasing development of infrastructure systems in urban areas of China, many
subway tunnels are being constructed near existing subway lines. Shield tunneling …

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 …

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 …

This paper presents a case of closely spaced twin tunnels excavated beneath other closely
spaced existing twin tunnels in Beijing, China. The existing twin tunnels were previously …
