Normal pressures on walls of subterranean structures
Conclusions 1. Modeling of cohesive soils with respect to parameter c is admissible for large-scale experiments. 2. The use of rolling-friction units at the contact between enclosing walls of narrow flumes and the soil effectively provides fulfillment of the initial conditions of the two-dimensional problem of elasticity theory. 3. The functions σ=σ(U) obtained have a pronounced nonlinear character. In undermined territories, where considerable displacements are realized, the use of a linear relation for calculation is unsound. 4. The arching effect is manifested in the distribution of lateral pressure on flexible walls, which should be expected to be greater, the higher the flexibility index of the element. 5. A comparison of the experimental data with the calculated with respect to lateral earth pressure shows imperfection of the existing method of calculating walls of belowground storage structures for horizontal compressive strains of an undermined base and the need to correct it.
