Ishchenko Y. Stabilization of soil deformations in conditions of dense urban development and in green construction

The purpose of this work is to develop applied methods for calculating the stress-strain state (SSS) of anti-landslide structures (ALS) in conditions of dense urban development and taking into account the requirements of green construction. In the dissertation experimental monitoring geodetic researches and mathematical modeling of SSS of ALS are carried out. For the first time, a comprehensive applied method of calculating the SSS of ALS in conditions of dense urban development and soil accidents, as well as taking into account the requirements of "green" construction has been developed. It allows you to gradually check the operation of the structure in the landslide for "crawling" and "pushing" and to assess the stability of the soil and determine the internal efforts to check the strength of the sections of ALS piles in terms of material resistance. The proposed integrated approach was implemented in the installation of ALS for a number of facilities. It allowed to stabilize and stop soil accidents and disturbances, to make economically and constructively expedient decisions on retaining structures, which ensure reliable operation of the upper buildings and the stability of the surrounding landslide-prone areas. Both geotechnical offline monitoring of ALS by engineering and geodetic methods and geotechnical online monitoring were further developed. The method of calculating landslide slopes to obtain shear pressure on the ALS to meet the new regulatory requirements has been improved. The author took part in development of seven normative documents of the Ministry of Regional Development of Ukraine on the bases, foundations, ALS, walls of ditches and landslide hazards, which were put into effect during 2000-2020.
