An effective method of explosive compaction of hydraulic structures foundations
If an explosive compaction method is used, there are two ways to blast charges in each turn: simultaneous and consecutive. This paper presents the results of theoretical studies, field trials and pilot sealing in production conditions, proving the effectiveness of the method of sequential detonation compared to the simultaneous one with base soils compacting on site. The conducted theoretical studies have shown that sequential detonation of neighboring charges with the time interval Δt that is smaller than the time of compaction of liquefied soil base layer t UP1 from previous charge multiple destruction of soil structure occurs with its consolidation within the limits of the compacted base. The obtained results of experimental trials have showed an increase in the relative values of average and maximal settlement on the site with sequential detonation compared with the one with the simultaneous one. Accordingly, the resistance of the implementation of the static probe tip Q3 increased to the values that showed a solid build of sand bases after compacting using the method of sequential detonation of charges.
