Overview of the problem of construction low-rise buildings on swelling clays
In this paper problems of building low-rise constructions on swelling clay are investigated. The ways of the decision of the given problems both at a design stage, and after construction stage are given. The purpose of scientific researches was to develop recommendations for the construction of low-rise buildings on claystones in the Perm city. The main methods of research in this topic are theoretical analysis and the study of scientific literature. In the course of this research the search for scientific and technical literature was searched, the information was analyzed then the most important things were determined for future research in topic of construction on swelling claystones. Main conclusions on the review: 1) claystones of Perm refer to swelling clays and this property should be taken into account when designing the foundations of low-rise buildings on these clays; 2) before the construction of the building on claystones the following measures can be envisaged: the construction of cushions from soil that does not have swelling properties; application of compensating pillows; preliminary soil soaking; 3) if the measures for eliminate the negative impact of the soil swelling process were not provided before the construction and the building received uneven deformations, the following measures could be envisaged: reinforcement of load-bearing structures with metal belts; increase in pressure on the base of the foundation through the superstructure; deliberate soaking of the swelling soil.
