ASSESSMENT OF INFLUENCE OF THE COEFFICIENT OF LATERAL EARTH PRESSURE ON STABILITY OF "FOUNDATION BASE - UNDERGROUND MINE" SYSTEM
The results of the solution to the examples illustrating the degree of mutual influence of the objects of “strip foundation — underground mine” system at various values of the coefficient of lateral earth pressure are given in the article. While finding solutions the computer program, in which finite element method is formalized, was used. The assessment of mutual influence of the objects of the considered system is carried out on the basis of the results of the analysis of the process of formation and development of areas of plastic flows in the soil mass inclosing the system. It is established that numerical values of “safe” distances and depths for “strip foundation — underground mine” under all other equal conditions are the functions of the coefficient of lateral earth pressure both in case of buried, and in case of the foundation daylight surface.
