AN INTERIM SLOPE FAILURE INVOLVING LEACHATE RECIRCULATION

摘要

leachate recirculation and/or surface infiltration can adversely affect slope stability and should be included in stability analyses, (ⅱ) failure to successfully manage surface runoff can result in the buildup of piezometric pressures, (ⅲ ) leachate recirculation using vertical wells can cause differential settlement that can facilitate ponding and infiltration of surface water, (ⅳ) a stability evaluation of interim slopes should be conducted even though it may not be required by regulations, and (ⅴ) state-of-practice interface testing and stability analyses could have been used to predict this failure.
