Accounting for Changes of Silty-Clay Soils Characteristics in the Ground Base of Buildings and Structures in the Process of Flooding of Territories
摘要
The article considers the problem of flooding of territories both in Russia and abroad. The authors give the diagram of the main sources and causes of flooding, as well as a classification of the consequences of flooding areas. They present the laboratory test results of physical soil properties changes and of mechanical soil properties changes, such as: oedometric modulus of deformation; the angle of internal friction and intercept cohesion. Analysis of the results show the negative effect of soil water saturation on the soils mechanical characteristics. The laboratory tests allowed the authors of the article to get the results of numerical modeling of forecasting the development of the geotechnical situation during the construction of a multi-storied residential building with an underground floor. This was done in the conditions of a possible increase of groundwater levels, which has calculated additionally. The article gives the forecast of the development area flooding considering two types of foundation (slab and strip).
