Abstract: Based on domestic first existing pit underground space development project-foding palace, characteristics and difficulties of existing pit geotechnical engineering comprehensive treatment projects were expounded, the general design steps were introduced, geotechnical engineering comprehensive treatment methods of existing pit were proposed. Some useful results of slope long-term and seismic stability calculation, along with large three-dimensional finite element calculation results were given, which provide a reference for similar projects.

Keywords: existing pit; underground space development; geotechnical engineering; comprehensive treatment
