Great attention must be paid to the safety and serviceability of existing tunnels when new
tunnels are constructed nearby in soft soils. In this study, the influence of pipe-jacking …

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 …

Tunnel excavation below existing tunnels produces ultimate and serviceability problems to
the existing tunnels. The behaviours of induced stresses on the existing tunnels haven't yet …

To address the challenges of low modeling efficiency and data loss in traditional methods,
an automated numerical simulation analysis framework is proposed to enhance the safety …

The interaction between a shield machine and the ground is a complicated problem
involving numerous extrinsic and intrinsic factors. Machine learning (ML) algorithms have …

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 …

The shield tunneling along the curve section is widespread in cities. This paper proposes a
ground loss model for shield tunneling along such sections. A prediction formula for the …

To accurately evaluate the safety risk status of buildings adjacent to karst shield construction
areas, a safety evaluation standard for buildings adjacent to shield construction in karst …

To solve the problem that the traditional fuzzy Analytic Hierarchy Process (FAHP) cannot
reflect the influence of prominent risk indexes on the evaluation results, a new risk …

A case of Qinghuayuan tunnel excavation below the existing Bei**g Subway Line 10 is
presented. The new Qinghuayuan tunnel, part of the Bei**g-Zhangjiakou High-speed …
