///80% of engineering area of Pangang new base is the backfill field of “Xigeda” soil, which results in negative friction resistance to the pile. The negative friction resistance experiment on the spot shows that there is more consolidation sinking under the accumulation load of upper backfill soil, which can cause negative friction resistance to the pile.
