摘要
According to the geological conditions of the large sandstone pit and the peripheral conditions, the application of vibor-replacement stone column, dynamic replacement and dynamic composite foundation treatment and heavy compacted crushing stone pile in Shangzhuangdonglu backfill roadbed of sandstone pit was introduced. At high water level, for the sandstone pit back-filled with soft soil and construction waste, vibro-replacement stone column was taken as the seepage tunnel. For the backfill roadbed at both sides of bridge pile, the scheme of heavy compacted crushing stone pile was used in order to reduce the impact to bridge pile.
