Blast Induced Soil Liquefaction - State-of-the-Art
This paper reviews blast induced soil liquefaction and describes an experimental laboratory testing program being conducted in the Civil Engineering Department's Geotechnical Engineering Laboratory at Colorado State University. The study of the behavior of water saturated sands under shock loadings is being conducted to evaluate potential blast induced changes in dynamic soil properties and soil shear strength loss (liquefaction). The facility is capable of generating single and multiple shock pulses with milli-second rise times, peak stress amplitudes of up to 35,000 KPa (5000 psi), peak particle velocities of 1000 cm per second (400 in. per sec.) and peak accelerations of 2,000 g. Of major interest is the behavior of the water pressure in the soil, both during and after the passage of the stress wave, as a function of strain, soil density, initial confining stress and the number of loadings. The information gained from the experiments will assist in improving ground shock prediction techniques for water saturated sands. (Author)
