Issue of construction of facilities in areas of weak saturated soils is becoming particularly relevant in recent years. This problem applies especially to objects of oil and gas industry. Saturated soils are characterized by a filtration anisotropy, an inhomogeneity and an ability to liquefy in violation of their structure because of water content. Therefore, the study of bearing capacity of such soils in the process of consolidation has significant practical importance in ensuring the reliability of structures. The formulation, the method and the algorithm for calculating the stress-strain state of weak saturated soils is described in this article. Solution of the consolidation task is based on the model of body forces of threecomponent soil considering the elastic-plastic deformation of its skeleton. Some results of calculations have been shown in this article.
