ResumoThe sixth chapter presents solutions of spatial problems of applied geomechanics related to variation of pore pressure in the soil. The influence of the pore pressure decline on the soil settlement and cracking as well as the induced seismicity and other environmental hazards due to pumping out gas and oil deposits or intense removal of underground water at industrial or civil engineering is discussed. The methods for numerical modelling of soil mass deformations due to the reduction of the pore pressure are described. The approach is based on the application of integral representations for displacements in a half-space saturated with liquid (or gas) according to the theory of linear pore-elasticity (filtration consolidation). Spatial deformation of the earth surface due to operating horizontal gas-and-oil wells or water drains is studied with the account of the run-off mode. Finally, the results for boundary-element solutions of the spatial contract interaction of structures with the soil at reduced pore pressure are presented.
