The research work considers the problems associated with Geoecological factors, related to the soil mechanics and foundation engineering. The scientific relevance is revealed, taking under consideration the fact, that special attention is paid to its role and the possibility of using genecology in solving environmental problems in modern conditions in soil mechanics development, analyzing and assessing the changes, taking place under the influence of natural and man-made impact, in the rational use of water, land, mineral and energy resources; in ensuring the safe living of people and reducing harmful effects on the environment as a result of natural and man-made disasters and various disasters, as well. In addition, the influence of Geoecological factors on the precipitation of foundations, calculated, concerning deformation anisotropy of base soils, is considered. The main types of Geoecological factors and the negative consequences of all these factors influence are given. The analysis of raising and lowering groundwater level effect on the carrying capacity of anisotropic soil foundations and precipitation of foundations was carried out. The role and necessity of using environmental impact assessment, as well as a comprehensive method of research and forecasting development of geological risk factors, are noted.

Излагается практический метод расчета осадок фундаментов с учетом анизотропии грунтов основания. Он основан на методике расчета деформаций грунтовых оснований по действующей нормативной документации-Своду правил СП 22.13330.2011 (Актуализированной редакции СНиП 2.02.01-83*. Основания зданий и сооружений). Предложенный метод предусматривает учет анизотропии грунтов при определении расчетного сопротивления грунта R под подошвой фундаментов сооружения (назначении размеров их подошвы) и расчете осадок жестких фундаментов S методом послойного суммирования деформаций. Для учета анизотропных свойств грунтов предлагается введение в расчет коэффициентов влияния анизотропии грунта k и K, зависящих от показателя анизотропии грунта  и напряженно-деформированного состояния основания (вида фундамента). Ключевые слова: осадки фундаментов, деформационная анизотропия грунтов, метод послойного суммирования, расчетное сопротивление грунта основания.

The article discusses ways to organize the work of students and teachers in remote work mode. The high efficiency of the point-rating system (PRS) for evaluating independent work in the conditions of distance learning is shown. A study was conducted on the preparation of training and monitoring activities for online classes. The issues of organizing lectures and laboratory classes, as well as conducting training practice during the period of remote work are considered. Internet opens up wide opportunities in the process of electronic textbooks on humanitarian disciplines creating. The technologies’ specifics allow making direct links to resources located in the worldwide network. Many experts believe that Internet technology is a revolutionary breakthrough, surpassing the importance of a personal computer appearance. Currently, there is a significant increase in the share of test passing in remote mode. For the development of electronic tests, there are many software tools that allow you to develop them according to a teacher preference. The important selection criteria are accessibility, the ease of use, the absence of any additional knowledge and skills, as well as the utmost clarity and comprehensibility of the proposed actions

The article contains recommendations prepared for “SP 22.13330.2016” foundations of buildings and structures”, where it is proposed to apply and take into account the deformation anisotropy in the calculations of ground bases. Consideration of deformation anisotropy is possible if there are reliable methods for predicting the stress-strain state (VAT) of soil bases. The existing calculation methods are based on the application of linear deformable medium theories. Over time, it becomes clear that the main provisions of the linear elasticity theory you can use it to describe underground areas, but with large adjustments, which leads to the development of new computational methods that take into account the deformation anisotropy.
