Geotechnical Analysis of Structural Behaviour Under Complex Geological Engineering Conditions

The article deals with the effect the geological engineering conditions have on the behaviour of structures under conditions of North-Western soft soils. A structural survey conducted at an oil refinery in the Leningrad region showed numerous faults and damages caused by settlements of the bearing structures and their foundations. Traces of leakages on the retaining walls of the pumphouse as well as next to the pipeline inlets witness a man-triggered raise of the ground water level. Crack formation in bottoms and walls of the aerotanks and sludge tanks was also denoted. It might be caused by the reduction of foundation soil bearing capacity. In its turn, deterioration of physical and mechanical features of the foundation soil is linked to the change in the hydrological regime of the area, which is proved by rich seepage of ground waters through the cracks in tanks. Having analyzed the structural and geological engineering conditions the authors recommend elaborating and performing a project to restore the proper working order of structures.
