The project decisions’ assessment algorithm for the foundation pit fencing based on the Theory of Active Systems

Abstract

Currently, a lot of new construction is underway in the large cities and megacities territories. Large residential complexes and shopping centers are erected at the sites of former industrial zones and factories. The issue of the accidents in foundation pits arising from the errors in their barriers’ projecting has recently been an acute question. And this is directly related to the fact that construction has to be carried out in very difficult straitened development conditions with the presence of existing utilities and underground facilities. The main designer’s task is the selection of an optimal project solution. Any project decision for the foundation pit barrier is characterized by both the technical characteristics, in particular the materials used, and its construction cost. Therefore, the designer faces a difficult question of the price and quality ratio for this project decision. And it is complicated by the fact that the specific engineering and geological conditions imply the possibility of various project decisions for the foundation pit fencing and the materials corresponding to the calculations results for the limiting states. This paper describes in detail the methodology for assessing the project decisions for foundation pit fencing and the choice of the materials used in barriers’ design based on the active systems theory.
