Modern urban policies, particularly in major towns, involve the active use of underground space that poses the problem of assessing the impact of excavation on the existing buildings as one of the most urgent. Surface and semi-closed construction methods are currently widespread in the process of urban civil and transport underground facilities construction. The depth of excavation can reach 30 m, but more often, in everyday practice common foundation pits have shallower depth, accommodating 2—4 underground levels (6—12 m).
In the process of solving such problems not only the forces occurring in the foundation pit fence are of great interest, but also a quantitative change in the stress-strain state of the rock mass. In modern engineering practice in order to solve them numerical methods based on the finite element method are widely applied, which can quantify soil stress-strain state.
In this study, the authors present the investigation of the influence of various factors within their variation on the additional deformations of adjacent buildings located in the influence zone, using the design of experiment method. The study is based on 3-dimensional numerical simulation with the use of finite element method. Such calculated factors were taken: the depth of excavation (X1), modulus of deformation (X2), the distance to the building (X3) and distributed load of the building (X4).
As a result, regression equations to determine the maximum additional deformation of building and horizontal displacement of the pit fence were derived from the calculations carried out. Also, the graphs describing these dependencies and illustrating the effect of each factor were presented
