CALCULATION OF FOUNDATION PRECIPITATION USING THE PLAXIS 2D PROGRAM

In this article, the layout of the building was calculated using the Plaxis 2D program. The building is a 5-storey business center located in Astana. The main purpose of the article is to clarify the progress of unloading loads on the foundation and a full explanation of the changes occurring in the foundation. When calculating a building, the calculation is considered in 5 stages. At the first stage, a protective wall of the pit is introduced. At the second stage, the pit is excavated to 1.5 meters and anchors are installed to ensure the stability of the protective wall. At the third stage, the pit is completely excavated. The total depth is 3 meters. At the fourth stage, a grillboard is laid, on top of which a load is applied to three floors of the building. At the fifth stage, the load on a full-fledged building is given. The full load on the building was removed from 5 floors. The most important difference of this report is the protective wall that will be installed in the pit. In an area where there are many buildings, there are many difficulties for carrying out construction work. One of them is geological heterogeneities caused by falling loads. This has a negative impact not only on buildings under construction, but also on neighboring buildings that have already been built. The protective wall ensures that when digging the foundation pit, the foundation will not crumble from the side and the course of construction will not have a negative impact on neighboring buildings. For this reason, a retaining wall is used
