Mathematical modeling of charge depth restoration in loess compacted by hydraulic blasting

Elena О. Tarasenko, Galina V. Tarasenko

Abstract


Mathematical modeling of loess compaction is a pressing issue in both theory and practice. In engineering, deep hydraulic blast compaction is widely used during the design phase of construction projects on thick subsidence soils. The analysis of geological systems necessitates solving inverse problems within the mathematical model under study. This paper addresses the problem of reconstructing the depth of an explosive charge. Analytical and numerical solutions are constructed for the inverse problem: with and without soil ejection onto the construction site surface. A computational software experiment was conducted to estimate depth values with a specified accuracy. Successive approximations to the solution of the inverse problem are constructed using an iterative method. The adequacy of the proposed approach to the data of in-kind compaction of the construction site is demonstrated.
