This article is an example of the calculation of a foundation monolithic slab using void formers during the construction of an apartment complex consisting of three buildings located on one stylobation. The issue of economy in the construction of a hollow core base slab compared to a solid one, by reducing the volume of concrete and reinforcement due to the location of liners in the neutral zone of concrete, is considered. At the same time, the bearing capacity and rigidity of the structure should remain at the same level.

This work solves the current task of construction on the landslide slope of the escalator gallery. The purpose of this work is to analyze and optimize various methods of stabilization of the soil mass and to identify the optimal solution for its strengthening. As a result of the calculations carried out, the most suitable option for strengthening the slope was found, which simultaneously had low material consumption and provided sufficient stability of the slope.

Based on the data of physical and mechanical properties of soils obtained at various construction sites in Moscow, the article discusses in detail the issues of soil compaction and determination of bearing capacity. The article describes various methods of soil compaction, which must be taken into account to determine the value of the physical and mechanical characteristics of the soils laid down in the project. It is especially important at the initial stage to determine the necessary parameters of the compacted base. The described dependences of the deformation modulus and the compaction coefficient for the artificial base were carried out in comparison with engineering and geological data obtained from real objects in the city of Moscow. The analysis of the results obtained for sands with different granulometric composition was carried out and graphs of the dependencies of the data obtained were constructed. The article also describes the controlled parameters when using a compacted sand cushion as an artificial base.

This article is an example of the calculation of a foundation monolithic slab using void formers during the construction of an apartment complex consisting of three buildings located on one stylobation. In this example, we consider several options for calculating multi-hollow foundation slabs in order to determine the most cost-effective design. At the same time, a multi-hollow foundation slab should have the same rigidity and load-bearing capacity as usual.

The purpose of this work was to determine the increase of the limit load when resting the foundation slab on the ground at a different pitch of piles and their different length. The main task is to calculate the combined pile-slab foundation. The hypothesis was that when the foundation slab in the work, the bearing capacity of the entire structure increases. This foundation was calculated using the Plaxis 3D design software complex. In this article, we have determined the value by which the ultimate load on the combined pile-slab foundation increases when the slab rests on soil.
