ABSTRACT
Earth structures are often used in military and civilian applications to protect
personnel and property from accidental detonation of stored explosives,
munitions, and ammunition plants. The advantages of reinforced soil structures
lie in their cost-effectiveness, rapid construction, and minimal use of occupied
ground area and high tolerance for differential settlements. They are also able to
impede the propagation of a blast at ground level and absorb high levels of
energy due to their high damping properties and great tolerance for deformation
before collapse. In using geosynthetics as facings and reinforcements, the
reinforced soil structures not only can absorb fragments from cased weapon
explosion, but also are not subjected to brittle fracture like concrete after
blasting and hence minimize the dispersal of flying debris. They are also
resistant to multiple blasting.
