THE ANALYSIS OF INTENSE-DEFORMED MONOLITHIC CONCRETE STRIP STATE OF UNDERGROUND STRUCTURES OF NONCIRCULAR OUTLINE
The research results of intense deformed state (IDS) of the crepe and soil massif of un-derground structures having a non-circular outline with a depth of laying up to 50 m in unstable al-luvial rocks with dumps from 0.3 to 0.7 m are presented. The study was carried out by means of modeling the IDS...

| description | The research results of intense deformed state (IDS) of the crepe and soil massif of un-derground structures having a non-circular outline with a depth of laying up to 50 m in unstable al-luvial rocks with dumps from 0.3 to 0.7 m are presented. The study was carried out by means of modeling the IDS of the soil massif and the hardening concrete of the monolithic support, erected after slaughter moving. To implement the proposed technological solutions ensuring the fixing of underground structures with monolithic concrete, it is necessary to use particularly fast solidifying compounds to exclude the use of temporary crepe. Based on the studies of a number of modifiers, various changes in mechanical properties of the most effective compositions have been established, which are used to simulate the concrete crepe of structures with time-varying characteristics.
Purpose: the basis for using resource-saving technology for the construction of underground structures in a non-circular outline in a soil massif.
Methods and methodology of the work: the studies were carried out by means of the finite element method (FEM) using the optimal design of the experiment.
Results: stress distributions were obtained in the hardening concrete crepe structures, stress concentration zones were established, displacement values in the soil massif and their spread on the surface were recieved.
Areas of the result application: the results of research work can be used in the design of options for the construction of underground structures. |
