A 5 m deep deposit of sand and silt containing organic layers is to be compacted using explosives placed in the boreholes located 8 m apart on a square grid. It is intended to create pore pressures which are at least equal to 80% of the effective overburden pressure. Estimate how many kg of TNT have to be distributed in each borehole in order to achieve this degree of liquefaction. How much is that per cubic meter of compacted soil?
