An Analytical Model of Seepage Field for Symmetrical Underwater Tunnels [PDF]

open access: yesSymmetry, 2018
Based on the mirror image method and superposition principle, an analytical model of seepage field for symmetrical underwater tunnels is proposed. The condition is assumed as two-dimensional steady water inflow into symmetrical and horizontal underwater tunnels in a fully saturated, homogeneous, isotropic, and semi-infinite aquifer.

Study on the Law of Influence of Seepage Field Anomalies on Displacement Field Induced by Leakage of Enclosure Structure

open access: yesApplied Sciences, 2022
The leakage of an enclosure structure will cause abnormal changes in the seepage flow field, which in turn can lead to the deformation of the enclosure structure and affect the surrounding geotechnical body.

Analytical Solution of Seepage Field in Karst Tunnel [PDF]

open access: yesAdvances in Civil Engineering, 2018
An analytical solution for the seepage field in water‐filled karst tunnel is derived based on the inversion of complex function and groundwater hydraulics theory. The solution considers the distance between the tunnel and the cavern, the size of the cavern, and the properties of the lining structure, such as the permeability coefficient as well as the ...

Water exclusion from tunnel cavities spanning a water table [PDF]

open access: yes, 2005
It is simply shown that the analysis giving the critical shape of tunnel cavities situated on a freely draining permeable substratum for water exclusion with vertical drainage through the saturated capillary fringe, can be extended to the situation where
