The object of the research is the forecast of seismic resistance when strengthening the soil foundations of structures. The purpose of the work is to numerically estimate the total increment of seismic intensity during artificial transformation and strengthening of foundation soils based on the results of geomechanical modeling. The study is based on classical mathematical methods for modeling soil foundations in a flat nonlinear setting. A new approach to determining the total increment of seismic intensity is presented, based on determining the ratio of the values of subsidence of the foundations of buildings and structures before and after soil strengthening. The paper presents the results of predicting changes in seismic resistance for real objects, obtained from the data of engineering and geological surveys and numerical computer models. It was found that due to the transformation of soil foundations, seismic resistance can decrease by more than 0.5 points. This technique can be used both to adjust the scoring for individual objects and to clarify the boundaries of seismic zones on OCP maps.

“…Skin grouting technologies and rock mass injection hardening [1][2][3][4][5][6][7][8] in combination with traditional types of supports were used in many mines of Kuznetsk Basin. Main reason for constraining application of injection hardening as a method to improve stability of mine workings [9][10][11][12][13][14][15] are the lack of geo-mechanical substantiation for excavation support considering grout mix water loss under pressure, the lack of structures and technology for construction of insulating shells around workings, as well as workable grouting complexes for injection operations Since most geological conditions of Kuzbass are complicated, the tasks outlined in the article are relevant.…”

The article presents brief description and results of laboratory and in-situ tests of frame support with backfilling of behind-anchoring space with grout. Characteristics of mining and geological conditions on the site of inclined conveyor shaft of Sychevskiy-I mine-section, A.D. Ruban Mine (JSC SUEK-Kuzbass) has been given. Grouting quality has been tested according to described technology, strength characteristics of cement and degree of grout mix influence on the surrounding rock mass has been determined. It is figured out that reinforced canvas use as a between-frame overlap increases cement strength. Some recommendations regarding the use of reinforced canvas as a grouting material have been formulated.
