In this paper, transverse vibrations of thin circular plates with guided edge and resting on Winkler foundation have been studied on the basis of Classical Plate Theory. Parametric investigations on the vibration of circular plates resting on elastic foundation have been carried out with respect to various foundation stiffness parameters. Twelve vibration modes are presented. The location of th...

Because of difficulty in inspection and retrofit of foundation in comparison with other elements, the common design philosophy is to avoid any nonlinear deformation in the foundation. This paper shows that by employing controlled foundation nonlinearity, in predetermined sections with arrangements for inspection and retrofit, it is possible to reduce seismic demand on superstructure. Localizing...

In dam construction, the actual depth to adequate foundation materials at a site is known with certainty only at the points of exploration. The foundation objective serves as a descriptive tool to convey design intent information to construction engineering staff and the contractor. The selection of the most effective approach, or approaches, usually depends on site geology and the amount of av...

Foundation dewatering combined with a waterproof curtain is widely applied to ensure the safety of foundation pit in areas multi-aquifer–aquitard alternative strata. The buried depth diaphragm wall can influence environmental effect due obviously. This paper investigates impact on groundwater drawdown considering anisotropic permeability aquifer. Numerical simulation conducted based an engineer...

the editorial by jeremy shiffman, “knowledge, moral claims and the exercise of power in global health”, highlights the influence on global health priority-setting of individuals and organizations that do not have a formal political mandate. this sheds light on the way key functions in global health depend on private funding, particularly from the bill & melinda gates foundation.

Due to the fluctuation of bearing stratum and distinct properties soil layer, buried depth pile foundation will differ from each other as well. In practical construction, since designed length is not definitely consistent with actual length, masses piles be required cut off or supplemented, resulting in huge cost waste potential safety hazards. Accordingly, prediction great significance constru...

There are some artificial and natural materials on foundation of heap leaching structures. Geomembrane liner is the most important artificial isolated layer of these structures. The thickness of this layer is about 1 to 2 mm. Foundation overall settlement of such structures changes the primary length of the geomembrane layer. If the strain of geomembrane is more than allowable one, the layer wi...
