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 ...

Abstract: Tunneling in soft clay requires accurate estimation of the inner support pressure to prevent undesired ground settlement and maintain the overall soil stability. Previous researchers have shown that the stability factor ...

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 ...

Abstract: Ring foundations are widely used to support various types of offshore structures because of the cost-effective reason. Unlike the traditional circular foundations, very few studies were reported with regard to the bearing ...

Abstract: Road-related sinkholes are of great concerns nowadays, appearing frequently in media stories. In the undrained stability analysis, a dimensionless stability number that is known as Broms and Bennermark’s original stability ...

Abstract: Underground water main leakage is one of the main causes of instability of soils and sinkholes. In the event of a water main burst, the pressure is upward and hence the soil layer should be analyzed for blowout stability. ...

Abstract: Longitudinal inclined tunnels are commonly encountered in practical projects, yet limited studies are available on determining the stability of the tunnel face with the presence of longitudinal slopes, especially in ...
