The influence of prescribed mining damages on the strip foundation framework

Marian Świerczek

Abstrakt

This paper analyses the interaction between building structure and ground that was subjected to mining exploitation. The issues relating to the influence of the enforced horizontal strains of the ground surface on the foundation framework were formulated as a quasi-static contact problem with friction and unilateral constraints. The incremental discrete task resulting from FEM was solved by iterative method. Obtained displacements, contact stresses and internal forces in the framework, were compared to similar available in the literature. All necessary calculation were carried out using MSC Marc.
