Stress-strain state of high-rise building foundation when constructing a sheet-pile wall

In modern construction practice, when constructing deep pits in complex engineering-geological and hydrogeological conditions, sheet-pile walls are often used in the form of a monolithic reinforced concrete wall in soil. Compared to otherstructural types of fences, the sheet-pile wall in the soil has a number of advantages, such as the possibility of its installation in almost any engineeringgeological and hydrogeological conditions of construction sites, reliable protection of the pit fromflooding during its high-quality performance of works, and increased rigidity. However, the construction of the sheet-pile wall in the soil of this type has a significant impact on the stress-strain state of the soil massif containing it, which negatively affects not only the surrounding buildings, which manifests itself in the form of its additional settlement, but also leads to uneven deformations of the soil massif at the base of slab foundations of highrise buildings, which are erected, increasing theirtilt.But if in recent years a number of works have been devoted to the study of the impact of the installation of a wall in the soil on the additional subsidence of buildings in the surrounding development, which made it possible to establish the regularitiesof their development and develop effective protective measures, then the effect of the wall in the soil on settlement and tilting, buildings that erected in pits has practically not been studied, and their correct assessment is especially important during the construction of high-rise buildings, the tilts of which are strictly limited by current regulatory documents.In view of this, as well as in connection with the volume of construction of high-rise buildings, which is constantly increasing, the implementation of studies aimed at studying the influence of a pit sheet-pile wall in the form of a monolithic reinforced concrete wall in a soil on the settlements and tilts of high-rise buildings on a slab foundation with the aim of increasing the accuracy of their calculation should be considered an actual geotechnical task.The degree of influence of the distance from the sheet-pile wall to the edge of the slab, the depth of the wall into the soil below the bottom of the pit, the contact conditions of the soil massif from the side of the pit with the surface of the fence (soil-concrete), the deformation characteristics of the base and the load on the average settlements and tilts ofhigh-rise buildings on slab foundations were studied.
