METHOD FOR EVALUATING EXCAVATION SHORING DESIGN CONCEPTS

Abstract

Abstract. Aim.When conducting engineering and geological surveys at the conceptual stage of the feasibility study, it is necessary to create an automated system that allows the designer to take all possible factors into account and choose the most optimal design solution for the shoring of excavations.Method. The study is based on dynamic programming methods based on the principle of Bellman optimality. Logical convolution matrices are applied according to the dichotomy method.Results. As a result of the logical convolution of the aggregated criteria of the environmental parameters K12 along with the parameters of the surrounding buildings K34, a comprehensive assessment of the design solution for a foundation shoring fence is obtained such as to ensure the technical characteristics and safety of the development zone. However, a considerable influence on the choice of the design solution for the building envelope is exerted by the cost of its construction. Therefore, the indicator of a comprehensive assessment of the shoring fence considering the economic efficiency of the KOE is obtained by combining the indicator of a comprehensive assessment of the foundation shoring fence KO with the criterion of economic efficiency of the design decision K5.Conclusion. The analysis of methods for solving optimisation problems demonstrates that the method of complex estimates based on the theory of active systems is optimal for the task of evaluating design solutions for foundation shoring fences.
