The antifloating property of underground structures in areas with high underground water levels is a key design aspect. Evaluating the buoyancy forces acting on underground structures is complicated, particularly in the presence of confined water beneath the structures. Herein, the effects of the permeability coefficient of layered soil, hydraulic gradient, and embedment depth of the aquiclude on the buoyancy force acting on underground structures are investigated through three model tests: calibration of the test system, buoyancy force acting on a structure (...) located in homogeneous soil considering vertical direction seepage, and buoyancy force acting on a structure located in layered soil considering vertical seepage of confined water. The results show that the pore pressure along the structure and the buoyancy force acting on the underground structure considering seepage are greater than those obtained under hydrostatic conditions. The raising ratios of the pore pressure and buoyancy force are equal to the vertical hydraulic gradient when seepage occurs in homogeneous soil. In the presence of confined water, the raising ratio is significantly greater than the hydraulic gradient. In the cases studied herein, the raising ratio is approximately twice the hydraulic gradient. Simplified equations are proposed to calculate the buoyancy force acting on underground structures considering the vertical seepage of confined water. Finally, a finite element analysis is carried out to verify the conclusions obtained from the model test and the rationality of the proposed equations. (shrink)

This work argues that at populism's core is a rejection of pluralism. Populists will always claim that they and they alone represent the people and their true interests. Müller also shows that, contrary to conventional wisdom, populists can govern on the basis of their claim to exclusive moral representation of the people: if populists have enough power, they will end up creating an authoritarian state that excludes all those not considered part of the proper "people." The book proposes a number (...) of concrete strategies for how liberal democrats should best deal with populists and, in particular, how to counter their claims to speak exclusively for "the silent majority" or "the real people." - Provided by the publisher.
