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: Shales are the most common materials on the Earth's surface that are frequently encountered in various energy, environmental, and engineering applications. Numerically predicting the mechanical behavior of shales is of ...

Abstract: A new instability criterion based on the critical slope concept and the double strength reduction is proposed to evaluate the stability of slopes. In this method, the critical slope contour is determined by the slip-line ...

Abstract: Drilling with prestressed concrete pipe cased piles (DPC piles) introduces a novel methodology in the domains of energy conservation and environmental protection, utilizing nondisturbed, high-strength, prestressed concrete ...
