Abstract:
Taking three sand foundation treatment engineering in Yulin City, Shaanxi Province as an example, the method of water weigh down sand and the method of vibroflotaion without additional backfill materials to reinforce the sand foundation were analyzed and compared in sides of the application area, the depth to deal with and economy effect through the standard penetration test, static loading test and the determination of pore-solids ratio. The analytical results show that the method of vibroflotation without additional backfill materials has a wider application area. In the condition that the depth of foundation to be reinforced is larger, the ground water table is higher or the situation of fine silty sand, the method of vibroflotation without additional backfill materials can get a more obvious reinforcement effect compared the method of water weigh down sand; the method of vibroflotation without additional backfill materials is a good method of foundation treatment which has a wide application area, obvious reinforcement effect and good economy benefits. The method can be applied to reinforce the sand foundation.
