This page contains materials from my practice in the field of stress state and stability analysis of earthen and concrete dams, slopes, underground structures, soil and rock mechanics. I am happy to share my knowledge freely if it can be of help to colleagues, practicing engineers or students, with full and proper references to the sources.The materials presented here are curated from multiple sources which are cited in each resource. This page will be updated periodically.

Note: The content of the files is in Bulgarian, English, Russian.
