In the current situation of development of the underground space of cities, the main task is to ensure safety and maintain the normal operation of both the building under construction and existing buildings and structures located in the zone of influence of new construction. The article considers the design of the dividing screen in the form of a continuous vertical geotechnical solid, made of jet-grouting elements. The analysis of existing analytical and numerical methods of static calculation of such structures is carried out. A computational model of the screen structure in the form of a plate lying freely on a two-parameter elastic base and being under the influence of a distributed arbitrary load is proposed. The calculated simulation of the dividing screen operation at the stage of building operation is performed. The main factors influencing the distribution of internal forces in the screen design are determined.
