RISThree-Dimensional Analysis of Circular Tunnel Headings Using Broms and Bennermark’s Original Stability Number
Publisher: ASCE
Abstract: The stability of a tunnel face is described by the combined effects of surcharge load, self-weight of the soil, and internal supporting pressure. This combination can cause failure in either blowout or collapse. Since the ...
Stability Factors <i>F<sub>c</sub></i>, <i>F<sub>s</sub></i>, and <i>F<sub>γ</sub></i> for Twin Tunnels in Three Dimensions
Publisher: ASCE
Abstract: This paper aims to study the three-dimensional (3D) tunnel heading pressure of twin circular tunnels in a drained cohesive–frictional soil using a stability factor approach and finite-element limit analysis (FELA). The ...
