Circular and rectangular tunnel shapes are usually chosen when excavating at shallow
depths in urban areas. However, special-shaped tunnels such as sub-rectangular tunnels …

The response of tunnels subjected to seismic loading is a complex mechanism and depends
not only on the seismic nature but also on tunnel structure and surrounding soil properties …

Temperature differences between the surrounding ground and the tunnel lining will cause a
variation of the tunnel lining forces. The hyperstatic reaction method (HRM) could be …

现有研究中, 可高效地给出考虑Hoek-Brown 破坏准则的圆形隧道衬砌结构内力分布规律的研究
方法较少. 为探究考虑Hoek-Brown 破坏准则时的圆形隧道支护结构内力分布规律 …

In recent years, many different methods for calculating the structural forces caused by
earthquakes to be created in circular and rectangular tunnels have been devised. However …

Tunnels are an important component of the transportation and utility system of cities. They
are being constructed at an increasing rate to facilitate the need for space expansion in …

Temperature differences between the surrounding ground and the tunnel lining will cause a
variation of the tunnel lining forces. The hyperstatic reaction method (HRM) could be …

The principal purpose of this Ph. D. thesis is to study the behavior of subrectangular tunnels
under seismic conditions by using a finite difference method (FDM) and then a new quasi …
