摘要：Danger of emergence and extension of suffosionprocessesis considered on the example of some objects of the road infrastructure. Need of the analysis and accounting of suffosionrisk in construction and operation of highways is proved. The model which is showing the mechanism of suffosion destruction of soils, hidden from direct observation in natural conditions, is given. The results of the experiment which is directed for the studying the features of extension of slope suffosion process near Schmidt Direction Street of Moscow are presented. The possibility of forecasting of emergence and extension of suffusion processes under the influence of natural and technogenic factors, and also determination of the amount of the expected underground and surface suffosionmanifestations (zones of destruction, cavities, failures, decreasing, etc.) is shown. Conclusions of the initiating reasons of suffosion processes on objects of road infrastructure and some preliminary recommendations for their prevention are made.
