ASSESSMENT OF THE IMPACT OF FLOODING ON FOUNDATION DEFORMATIONS OF A RESIDENTIAL BUILDING IN KARAGANDA

Abstract

The article presents the results of a comprehensive assessment of a residential building with strip foundations operating under high moisture and groundwater flooding in the Vostok-2 microdistrict of Karaganda. The study was conducted using visual, instrumental, and analytical methods. It was found that the deformation modulus of sandy loam under natural moisture conditions is 11.8 MPa, while under water-saturated conditions it decreases to 5.9 MPa. The calculated foundation settlement under full water saturation reaches 12.25 cm, exceeding the normative value of 10 cm. It was determined that most deformations are formed in the upper soil layer. Calculations showed that the minimum thickness of the unsaturated bearing layer is 1.11 m, and the minimum groundwater lowering depth is 3.71 m, ensuring foundation stability. The obtained results can be used in the design of drainage systems and building operation under flooding conditions.
