Abstract: This paper investigates the stability of unlined rectangular tunnels in rock masses subjected to surcharge loading using adaptive finite element limit analysis based on the generalized Hoek-Brown failure criterion. Both ...

Abstract: In this paper, finite-element limit analysis (FELA) in conjunction with nonlinear programming was developed and applied to evaluate the stability of asymmetric parallel circular tunnels in cohesive-frictional soils subjected ...

Abstract: This study used adaptive finite-element limit analysis (AFELA) to calculate the undrained bearing capacity of strip footings placed adjacent to two-layered slopes. Both the upper bound (UB) and the lower bound (LB) of the ...

Abstract: Pigging technology is currently widely used in the oil and gas industry. The unstable movement of the pig in the pigging process after a water pressure test will not only affect the operation of pipes, but may even cause ...

Abstract: This study employed finite element limit analysis (FELA) to investigate the influence of eccentric loads on the bearing capacity of footings above single and double continuous voids. Upper bound theorem (UB), lower bound ...
