The management of stress-strain state of the bases for stabilizing uneven settlements

Abstract

One of the actual problems of modern construction is the development of methods for managing the stress state of the soil bases for its use in conditions favorable to the construction. Also, soil state management methods are used to protect existing buildings and structures from the negative impacts of new construction. One of the methods that can affect the stress-strain state is the technology of compensatory injection. The essence of the method consists in injecting an extra volume of a slowly hardening solute into the soil base placed in the path of propagation of an impact wave transmitted through the soil. Controlling the volume of the pumped material, a calculated stress-strain state of the soil massif is created, which ensures safe construction. The article contains theoretical foundations describing the processes and examples of numerical simulation of control processes of the stress-strain state of the base when tunneling under the building.
