Study on Mechanical Characteristics and Construction Control of the Railway Overlapping Tunnels
Frontiers in Earth Science, 2022 In tunnel engineering, newly built tunnels will disturb the surrounding strata and close-to-existing tunnels, which may cause secondary lining cracking and overall damage to existing tunnels.

Influencing factors for deformation of deep foundation pits in thick mud stratum
Yantu gongcheng xuebao, 2021 Zhuhai is located at the southern front of Pearl River Delta and has very typical soft soil geological conditions. Affected by various factors such as sedimentary environment, the physical and mechanical properties of Zhuhai soft soils are different from

Isomonodromic deformations along a stratum of the coalescence locus
Journal of Physics A: Mathematical and Theoretical, 2022 Abstract We consider deformations of a differential system with Poincaré rank 1 at infinity and Fuchsian singularity at zero along a stratum of a coalescence locus. We give necessary and sufficient conditions for the deformation to be strongly isomonodromic, both as an explicit Pfaffian system (integrable ...

Deformation characteristics and mechanism of deep subsize coal pillar of the tilted stratum [PDF]
Energy Science & Engineering, 2019 AbstractBased on the analysis of the monitoring data of surface displacement and internal multipoint displacement of coal pillars near three inclined strata roadways, which have similar burial depth and different surrounding rock conditions in a coal mine in the east China, the coal pillars’ stress change was combined with discontinuous numerical ...

Construction prediction and dynamic control of shield tunnel
Yantu gongcheng xuebao, 2019 It can not be ignored that the construction of shield tunnel in the proximity of the existing structures is risky. The stratum loss is the major cause of ground deformation during the construction process of shield tunnel.
