ABSTRACT
Computational analysis of influences of mining exploitation on certain frame bridge are described in this paper. Mining deformations of ground cause the coming into existence of internal additional forces in structures. The frame structure of the object causes that it is necessary to pay special attention to interaction of the structure and ground, which is coming into existence of internal additional forces in the structure. A distribution of inner strengths in the structure is determined in these elements of the object which are important for the safety. Method of static scheme changing as technical solution, which adapted construction to take additional loads from mining deformations of the area, is discussed. The example of computational analysis is given. A system of monitoring will let to control the risk of structure’s failure.
