Assessment of the Liquefaction Hazards Resulting from Explosive Removal of the Bird's Point-New Madrid Fuze Plug Levee

摘要

As a result of this study, it is concluded that: (1) No liquefaction should be expected at distances greater than 1275 ft from the 11,370-ft levee section. Therefore, the setback levee faces no liquefaction hazard from the explosion. (2) There will be no liquefaction occurring within Wickliffe, KY, or Cairo, IL, which are both well beyond the 1275-ft liquefaction hazard range. (3) No liquefaction should be caused by the explosive removal of the 6000-ft levee section. (4) Liquefaction might occur in the foundation of the 11,370-ft fuze plug and at the newly exposed end sections in the forward levee that will exist once the fuze plug is removed. The liquefaction could not extend to more than about 1000 ft from the ends of the explosive line.
