Alternant active and passive trapdoor problem: from experimental investigation to mathematical modeling
In the classical conception of the arching mechanism, the well-known trapdoor problem assumes distinctive modes (e.g., either active or passive mode) in the original geostatic overburden pressure. However, in ...
