| Title of the article | Study of changes in the stressed state of soil during cementation at a cultural heritage site |
| Abstract. | Problem statement. In the center of Tyumen, surrounded by dense urban (including historical) development, the construction of a five-story building with an expanded two-level underground space 6.3 m deep is currently being completed. The excavation of deep pits, unloading, and overloading of the soil base composed of silty-clay soils in constrained conditions contribute to additional settlement of the surrounding buildings, particularly affecting heritage buildings sensitive to such deformations. As part of emergency stabilization measures for the historical building’s settlement, soil cementation using the collar technology was performed. The purpose of the work is to investigate changes in the soil’s stress state during soil cementation by collar technology while work process of the emergency stabilization measures at a cultural heritage site. The object of research consists of silty-clay soils of stiff-plastic to soft-plastic consistency forming the soil base of the historical building, located within the influence zone of new construction involving deep excavation works. The subject of research is their stress state during and after emergency protective measures involving compensation grouting. Tasks include: - investigating changes in the stress state of the historical building’s silty-clay soil base during soil cementation by collar technology; - analyzing the stress relaxation process in silty-clay soils from soft-plastic to stiff-plastic consistency during and after grouting; - analyzing the results of compensation measures to stabilize the settlement of the cultural heritage site. Results. The main results of the study include new data on stress development in silty-clay soils of the historical building’s soil base during cementation by collar technology and its relaxation after the completion of the works. Conclusions. The ability to assess the impact of grout injection during soil cementation on changes in the stress state of various soils, enabling the prediction of their future behavior, highlights the practical significance and relevance of the research. |
