The quasi-rectangular tunnel represents a novel cross-section design, intended to
supersede the traditional circular and rectangular tunnel formats. Due to the limited capacity …

In underground mines, development headings such as tunnels and access are essential
structures of mining infrastructure. Blasting is the most preferred excavation method for ore …

The pouring interval will cause cold joints in concrete components, which reduce the safety
and reliability of structures. This study conducted a three-point-bending test on concrete …

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 …

The interaction mechanism between a two-lane shield tunnel and an existing tunnel during
oblique underpass is a matter of widespread concern in the engineering community, and …

Circular tunnels are the most popular shapes used in urban underground transportation
systems when mechanized tunneling is used for tunnel excavation. However, circular …

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 …

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 …

Circular tunnels are the most popular shapes used in urban underground transportation
