... imperfections, for example, due to damage during installation. The cement-bentonite material therefore must be of sufficiently low permeability, after reaction with the groundwater, to ensure that any imperfections in the geomembrane do not compromise the overall performance of the wall. A specification...

..., on quantifying the extent of spontaneous combustion in waste dumps from coal mines (see Kim and Chaiken, 1993). The major cause of spontaneous combustion is the exothermic reaction between atmospheric oxygen and the reactive carbonaceous materials. In the case of open cut mines, the overburden spoil piles can...

... ABSTRACT: Natural surface water and pore water in the subsoil is not an ideal, incompressible fluid. Small microscopic air (gas) bubbles are dispersed in the water, so the fluid shows a certain compressibility. Compressible pore water causes a delayed reaction of the pore water pressure on any...

The principal results are presented in the form of graphical nondimensional relationships that permit to value easily pile head deflection and maximal bending moment in the pile.

If tunnel ribs, wire mesh, lagging and perhaps shotcrete are immediately applied, it may be possible to support the crown and walls of the tunnel, but these sup- ports may not be able to provide adequate reaction against the grippers if backed by loose and broken...

... are a function of the de- flected shape of the structure. For mul- tiple footings, therefore, it is necessary to include the effects of soil-structure interaction in the theoretical formula- tion, as summarized below. Assume that the structure is under load but no settlement is permitted; therefore, the reaction...
